What is enrichment?
The term 'enrichment' implies that there is a quality improvement, but the word and the concept of environmental enrichment are often misused and are applied simply when changes are made to the environment or when the environment is made more complex.
Such changes or increases in complexity do not necessarily involve any improvement in the quality of the environment for the animals and the animal's welfare. Indeed, some changes may actually decrease the quality of some animals.
You need to understand how a particular environment impacts the animal; you should also focus on the outcomes for the animal when making changes to their environment. Only if we can demonstrate that the change to the environment has improved that environment for the animal welfare, then you can say that environmental enrichment has occurred and that the welfare of the animal has been improved.
It is important that when you are using any enrichment strategy within your facility, you are aware of or make sure that you research and assess the research findings as to any adverse consequences that may occur due to the enrichment strategy.
Enrichment gives animals something to think about, encourages exercise, and gives animals a degree of control of their environment by giving them choices. Basically, enrichment helps keep life interesting and challenging.
Enrichment strategies may include:
- Physical and psychological enrichment such as:
- Hiding food to encourage activity
- Long walks
- Brushing, patting etc…
- Social enrichment such as:
- Providing activities with other animals
- Sensory stimulation:
- Play music, audiobooks, and TV when not at home
- Provide scents in the area
Most animal species will have different types of enrichment, so you first need to look at the animal and then (if required) research the types of enrichment suitable for the species. If you are uncertain, speak with your supervisor to get their ideas and make sure you check out the organisational policies and procedures. There may be specific enrichment procedures for animals handled in the facility.
Olfactory and gustatory enrichment
Olfactory enrichment uses the animal’s sense of smell, and gustatory enrichment uses taste.
For both these types of enrichment, you could use:
- Stuffed paper bag with various objects (food, straw, other animal smells)
- Piercing holes in tubes and adding food that can be grabbed or fall out
- Healthy treats hidden in straws and a box can entertain for hours
- Hanging Ice block
- Food or some other reward is placed in the box, which encourages manipulation and play
- Scent-infused sacks are a simple form of olfactory enrichment
Case Study
At Happy Paws Animal Care, the team recognised the importance of providing mental and physical stimulation for animals in their care, particularly those who had been in the shelter for extended periods. To reduce stress, prevent boredom, and improve overall animal welfare, the staff developed and implemented a comprehensive enrichment program tailored to different species, including dogs, cats, and small animals.
Happy Paws cares for a wide range of animals, many of which arrive with behavioural issues stemming from neglect, abandonment, or long periods in confinement. Animals displaying signs of stress or boredom (e.g., pacing, barking, or destructive behaviour) were less likely to be adopted, and their quality of life in the shelter was negatively affected.
To address these issues, the staff at Happy Paws designed a structured enrichment program aimed at stimulating animals both mentally and physically, encouraging natural behaviours, and improving their emotional well-being. The ultimate goal was to make the animals more adoptable by showcasing them as well-adjusted, engaged pets.
Key Elements of the Enrichment Program:
- Environmental Enrichment: Providing animals with a dynamic and stimulating environment miming their natural habitat.
- Sensory Stimulation: Engaging the animals’ senses through different types of stimuli.
- Social Enrichment: Facilitating positive human-animal and animal-animal interactions.
- Cognitive Challenges: Introducing problem-solving tasks that require the animals to think and engage with their environment.

| Cats |

| Small Animals (Rabbits, Guinea Pigs) | Foraging and Chewing: Hay and fresh vegetables were hidden in different parts of their enclosures to encourage natural foraging behaviours. Chew toys made of safe materials helped maintain dental health while providing a productive outlet for natural gnawing instincts.
|
Implementation Process:
- Planning and Development: The staff at Happy Paws started by researching best practices for enrichment and consulting with veterinarians and animal behaviourists to design appropriate activities for the animals in their care. The team identified the specific needs of each species and created an enrichment plan tailored to individual animals' behaviours and preferences.
- Resource Allocation: Enrichment tools, toys, and structures were sourced through donations and partnerships with local businesses. Staff and volunteers helped build agility courses and install climbing structures for cats. The shelter also repurposed household items such as cardboard boxes, plastic bottles, and old blankets for sensory and foraging activities.
- Training and Participation: Staff were trained in how to implement and monitor enrichment activities safely. Volunteers were involved in daily enrichment sessions, including walking the dogs, playing with cats, and interacting with small animals.
- Evaluation and Adjustment: The team regularly evaluated the program's effectiveness by observing changes in the animals' behaviour and overall well-being. Adjustments were made based on the animals' responses, and new enrichment activities were introduced to keep things varied and interesting. If an animal’s behaviour improved significantly (e.g., reduced anxiety, less barking or pacing), it was noted as a successful aspect of the program.
Results:
- Improved Behaviour: Many animals showed a marked improvement in behaviour after the enrichment program was implemented. Dogs were less anxious and better behaved during adoption events, while cats became more interactive and less stressed. For small animals, the enrichment activities reduced boredom-related behaviours like excessive chewing or aggression.
- Higher Adoption Rates: Happier, more relaxed animals were more appealing to potential adopters. The staff noticed that animals who participated in enrichment programs were adopted more quickly than those who didn’t engage in enrichment.
- Reduced Stress and Anxiety: By giving animals outlets to engage in natural behaviours, their stress levels were significantly reduced, improving their overall quality of life during their stay at the shelter.
The enrichment program at Happy Paws Animal Care was a successful initiative that enhanced the mental and physical well-being of the animals in the shelter. By providing species-appropriate activities that engaged their natural instincts, the team improved behaviour, reduced stress, and increased adoption rates. The program has become an integral part of daily care at Happy Paws, demonstrating the importance of enrichment in maintaining the health and happiness of shelter animals.
While enrichment strategies are essential for promoting the well-being of animals, they can sometimes have unintended adverse consequences if not properly planned, executed, or monitored. It’s important to consider the potential risks when implementing these programs to ensure that the enrichment is beneficial and safe for the animals. Here are some of the possible adverse consequences of enrichment strategies:
Injury to Animals
- Physical Harm: Enrichment items that are not appropriately sized or designed can lead to injuries. For example, toys with sharp edges, small parts that can be swallowed, or objects that can trap limbs may cause cuts, choking, or entrapment.
- Over-Exertion: Physical enrichment, such as exercise equipment or play activities, can lead to over-exertion, particularly in animals with underlying health issues, elderly animals, or those not used to high activity levels.
- Incorrect Substrate or Climbing Equipment: Using inappropriate materials for species that dig or climb can result in falls, slips, or other accidents.
Increased Stress or Anxiety
- Over-Stimulation: Introducing too many enrichment activities or overly complex tasks can overwhelm animals, leading to stress rather than engagement. For example, too many toys in a small space can create confusion or anxiety, especially for more solitary animals.
- Disruption of Natural Behaviours: Enrichment that does not align with the animal’s natural behaviours or preferences may frustrate them. For example, social animals that are deprived of group interactions or solitary animals forced into social settings can experience heightened stress levels.
- Fear or Startling: Some enrichment items may frighten animals, especially those that are novel, noisy, or unpredictable. For instance, certain animals may fear a new toy with bright colours or loud sounds.
Aggression or Conflict Between Animals
-
Competition for Resources: Group enrichment activities can lead to competition, aggression, or dominance issues, particularly if the items provided are limited or highly valued. For example, feeding puzzles or toys that only one animal can access may result in fighting between animals.
- Disruption of Social Hierarchies: Introducing enrichment that disrupts the established social order in groups (e.g., primates or birds) can cause conflict, such as dominant animals monopolising resources and causing stress for lower-ranked individuals.
Health Risks
- Contamination and Disease Spread: Poorly cleaned enrichment items or food-related enrichment activities can lead to contamination, resulting in illness. For example, using food items that spoil quickly or fail to clean toys between uses can promote the spread of bacteria or fungi.
- Inappropriate Diets: Food-based enrichment, such as treats or puzzle feeders, may unintentionally lead to obesity or nutritional imbalances if the enrichment food isn’t appropriate for the species or is provided too frequently. Offering the wrong type of food (e.g., sugary treats for herbivores) can negatively impact their health.
- Allergic Reactions: Certain enrichment items, such as bedding or chewing toys, may cause allergic reactions in some animals. This is especially a concern if synthetic materials, chemicals, or non-natural items are introduced.
Frustration or Boredom
- Overly Simple Enrichment: If the enrichment activities are too easy or repetitive, animals may quickly become bored, resulting in frustration or undesirable behaviours, such as destructive chewing, pacing, or excessive vocalisation.
- Unsolvable Puzzles: On the other hand, puzzles or tasks that are too difficult may lead to frustration and stress, particularly if the animal cannot figure out how to retrieve the reward or complete the activity.
Invasive Impact on Natural Behaviours
- Disruption of Natural Cycles: Enrichment that interferes with natural behaviours, such as feeding, sleeping, or mating cycles, can have negative consequences. For example, enrichment provided at the wrong times may disrupt animals’ circadian rhythms, especially in nocturnal species.
- Over-Reliance on Human Interaction: In some cases, animals may become overly dependent on humans for enrichment if the program relies too heavily on human interaction, potentially limiting their natural behaviours, such as foraging or socialising with conspecifics.
Habituation
- Diminished Effectiveness: Repetitive use of the same enrichment items or activities may lead to habituation, where the animal becomes used to the stimulus and no longer finds it engaging. This can lead to boredom and a decline in the benefits of the enrichment program.
- Loss of Natural Instincts: In some cases, too much reliance on human-provided enrichment may weaken an animal’s natural survival instincts, particularly in wildlife rehabilitation or sanctuary settings where reintroduction into the wild is a goal.
Negative Impact on the Enclosure Environment
- Overcrowded Enclosures: Too many enrichment items, such as toys or structures, can overcrowd an animal’s space, reducing their ability to move freely. This can create stress and even lead to accidents or injury.
- Decreased Cleanliness: If not properly maintained, enrichment items can lead to a build-up of waste, debris, or food remnants in the enclosure, reducing overall hygiene and increasing the risk of illness.
- Environmental Degradation: In naturalistic enclosures, introducing certain types of enrichment (e.g., synthetic materials) may degrade the natural environment, harm plants, or affect the ecosystem in wildlife sanctuaries.
Misapplication of Enrichment
- Incorrect Species-Specific Enrichment: Providing enrichment unsuitable for the species (e.g., offering climbing structures to ground-dwelling animals or using scent-based enrichment with species that do not rely on scent) can result in confusion, stress, or injury.
- Overuse of Food-Based Enrichment: Relying too heavily on food-based enrichment, rather than a variety of activities, can lead to obesity or other health issues, as well as overfeeding if not monitored correctly.
Human Safety Risks
- Dangerous Animal Behaviour: In some cases, certain enrichment items may provoke overly aggressive or defensive responses from animals, putting handlers at risk. For instance, big cats or primates may become possessive over certain toys, leading to aggressive behaviours when staff try to remove or clean the items.
- Unsupervised Handling: Enrichment activities that require direct human interaction, such as playing with dogs or training birds, could result in injuries if the animals become over-excited or behave unpredictably.
If at any time you observe any adverse consequences to the enrichment strategy that has been put in place for an animal, it is important that you notify the appropriate person.
Case Study
At Happy Paws Animal Care, the staff always strive to implement enrichment programs that enhance the welfare of the animals. However, in one instance, an enrichment strategy for the dogs in their care led to unintended adverse consequences. This case study illustrates how an enrichment activity, while well-intended, caused overstimulation in some dogs, resulting in increased stress and undesirable behaviours.
The team at Happy Paws introduced a new daily enrichment routine involving high-energy activities for the dogs, particularly those that had been in the shelter for extended periods. They installed a new agility course with jumps, tunnels, and hurdles to keep the dogs active and to mentally stimulate them. The idea was to give the dogs an outlet for their energy, which would reduce boredom, improve fitness, and help with behaviour management. Initially, this enrichment activity was successful and showed positive results for many dogs.
However, the team noticed that some dogs began to display hyperactive and agitated behaviours after participating in the agility sessions. Instead of calming down after physical exertion, these dogs appeared more excitable and restless, leading to increased behaviours such as excessive barking, jumping, and even some incidents of aggression towards other dogs.
Adverse Consequences of the Enrichment Strategy:
- Overstimulation and Hyperactivity: While physical exercise is essential for a dog’s well-being, some of the more excitable dogs, particularly those with high-energy temperaments like Border Collies and Australian Shepherds, became overstimulated by the daily agility training. The high stimulation level from running, jumping, and constant physical activity led to hyperactive behaviours even after the enrichment sessions ended. Instead of burning off energy, these dogs became more restless and difficult to manage during the quieter parts of the day.
- Increased Stress Levels: The overstimulation caused by the agility course also resulted in elevated stress levels for some dogs. Dogs who were already prone to anxiety, such as rescue dogs that had experienced trauma, found the intense physical activity overwhelming. These dogs displayed signs of stress, such as panting, pacing, and shaking, even long after the enrichment sessions had concluded. The physical nature of the activities inadvertently increased their anxiety rather than reducing it.
- Behavioural Regression: Some dogs, especially those with behaviour issues related to excitement or control, began to regress in their training. Instead of learning to remain calm and composed, they associated the enrichment time with uncontrolled excitement. For instance, a Labrador mix named Buddy, who had previously made progress in learning to sit calmly before walks, began jumping up on staff members again in anticipation of the agility sessions. This regression was linked to the overstimulation caused by the high-energy enrichment.
- Aggression and Conflict: In a few cases, the heightened energy levels led to increased aggression among some dogs. For example, during group playtime after agility training, dogs that had become overly excited during the activity were more prone to conflict. An incident occurred where two dogs, who were usually friendly with each other, had a scuffle during playtime after both had participated in the agility course. Staff attributed this to the dogs' elevated arousal levels, which made it harder for them to regulate their emotions and behaviour.
Staff Response and Modifications:
- Assessment and Behavioural Observations: The staff at Happy Paws closely monitored the dogs’ behaviour and quickly noticed that the enrichment activities had unintended negative effects. They recorded instances of hyperactivity, stress, and aggression and began to review the suitability of the agility course for all dogs.
- Tailoring Enrichment to Individual Needs: The team realised that while physical exercise is crucial, it needs to be balanced with mental stimulation and relaxation, especially for dogs that are prone to overstimulation. They modified the enrichment program to be more personalised. High-energy dogs were still given access to the agility course, but for shorter, more structured periods, followed by calm-down exercises like sniffing games or quiet time in the sensory garden.
- Adding Calming Enrichment Activities: To counteract the overstimulation, the staff introduced calming activities, such as scent-based enrichment and foraging puzzles. These activities helped dogs wind down after physical exertion and provided mental stimulation without over-arousing them. Dogs that were more prone to stress or excitement were given these activities as an alternative to the agility course, ensuring they still received enrichment suited to their temperament.
- Rest Days and Balance: Another modification was introducing "rest days", where dogs were not engaged in high-energy activities but instead had more passive enrichment options like puzzle feeders, soothing music, and gentle human interaction. This balanced approach helped prevent burnout and overstimulation while ensuring the dogs remained mentally and physically healthy.
Lessons Learned:
- Not All Enrichment is Suitable for All Animals: Even positive enrichment activities can have adverse consequences if not tailored to the individual animal’s needs. In this case, some dogs thrived with physical exercise, while others became overstimulated. Understanding each animal’s temperament is critical in designing effective enrichment.
- Balance is Key: A well-rounded enrichment program must strike a balance between physical and mental stimulation, as well as rest. For some animals, high-energy activities should be supplemented with calming and mentally soothing options to prevent overstimulation.
- Observation and Flexibility: Continuous observation of animal behaviour is essential to gauge the success of an enrichment program. Being flexible and willing to adjust the program based on individual animal responses ensures that adverse effects are identified and corrected quickly.
Once you have conducted an enrichment program, and the items are no longer being used, then those items that have been used for the enrichment program must be either:
- Cleaned
- Decontaminated
- Sterilised
- Disposed of
- Replaced
Any of the above actions must be done by your facility policies and procedures, as well as any state or territory legislation and the Australian Veterinary Association guidelines.
What is the difference between cleaning, disinfecting and sterilising?
The differences between cleaning, disinfecting and sterilising include:
- Cleaning
- General removal of debris (dirt, food, faeces, blood, saliva and other body secretions)
- Reduces the amount of organic matter that contributes to the proliferation of bacteria and viruses
- Disinfection
- Removes most organisms present on surfaces that can cause infection or disease
- Sterilisation
- The killing or removal of all organisms

Case Study
At Happy Paws Animal Care, providing engaging and stimulating enrichment for the animals is a top priority. However, with daily use, enrichment items such as toys, puzzle feeders, and sensory objects can quickly become dirty or worn out, posing potential hygiene risks to the animals and diminishing the effectiveness of the enrichment. This case study examines how Happy Paws developed a routine for cleaning and replacing enrichment items to maintain hygiene standards and ensure that the animals received the best possible care.
Happy Paws has a variety of enrichment items for dogs, cats, and small animals to encourage physical activity, mental stimulation, and stress relief. These items include:
- Puzzle feeders and treat-dispensing toys for dogs and cats
- Chew toys and ropes for dogs
- Climbing structures and perches for cats
- Sensory boxes and tunnels for small animals
Over time, many of these items became soiled with saliva, food remnants, and dirt. Additionally, some of the toys, especially chew items, began to show signs of wear and tear, potentially posing a choking hazard. To prevent the spread of disease and ensure the items remained stimulating and safe, the team implemented a strategy for regular cleaning and timely replacement of enrichment items.
Issue:
Several dogs had developed minor skin irritations, and the veterinarian suspected that bacteria on shared toys could contribute to the problem. The cats had also started ignoring certain toys, as they had lost their scent and novelty after prolonged use. The staff realised that regularly cleaning and replacing enrichment items was essential to prevent health issues, maintain interest, and ensure the enrichment program continued to meet the animals' needs.
Cleaning and Replacement Strategy:
- Routine Cleaning Schedule: The team established a weekly cleaning schedule for all enrichment items, ensuring toys and equipment were sanitised regularly. High-use items, like food puzzles and chew toys, were cleaned more frequently (after each use) to prevent food residue buildup and reduce the risk of bacteria or mould.
- Dogs’ Toys and Puzzles: Toys like Kong chew toys, puzzle feeders, and ropes were washed daily. Rubber and plastic items were cleaned with pet-safe disinfectant, rinsed thoroughly, and air-dried. Fabric toys were laundered regularly. The team ensured toys were completely dry before returning them to prevent mould growth.
- Cats’ Enrichment: Cat toys, including balls, wands, and treat-dispensing toys, were cleaned at least weekly. Cat trees, perches, and scratching posts were spot-cleaned daily with pet-safe cleaning products and vacuumed regularly to remove fur, dust, and dander.
- Small Animals’ Toys: Tunnels, chew sticks, and sensory boxes for small animals like rabbits and guinea pigs were cleaned weekly. Tunnels were rinsed and sanitised, and chew sticks were replaced once they became overly worn. Bedding in sensory boxes was changed regularly, and any soiled material was removed immediately.
- Monitoring Item Wear and Tear: In addition to regular cleaning, the team at Happy Paws implemented a system to monitor the condition of enrichment items. Staff were trained to inspect toys daily for any signs of damage, such as fraying, cracks, or pieces that could be swallowed.
- Replacing Damaged Items: Toys that showed wear, such as frayed ropes, cracked plastic, or missing parts, were removed and replaced immediately. For dogs, chew toys were replaced regularly to avoid broken pieces becoming choking hazards. Cats’ scratching posts were replaced when the sisal became worn out, ensuring that the cats could still engage in satisfying scratching behaviours.
- Rotation of Toys: To maintain novelty and prevent boredom, the team also began rotating toys weekly. Each dog or cat was given a different set of toys each week to keep them engaged and excited about their environment. This also allowed toys to be cleaned and dried properly while other toys were used.
- Cleaning Protocol for Shared Spaces: Shared play areas and enrichment zones, such as the dog agility course or cat climbing area, were sanitised daily. Any toys used in communal spaces were cleaned immediately after group play sessions to prevent the spread of bacteria or parasites.
- Replacing and Introducing New Items:
- The team regularly replaced enrichment items that were too worn to be safely used. They sourced new toys through donations and partnerships with local pet stores. Additionally, they used DIY enrichment by creating new toys from household items, such as cardboard boxes or toilet paper rolls for the cats and small animals.
- Scent Reintroduction for Cats: To reignite interest in old toys for the cats, the team used catnip or other attractants. This gave older toys a new lease on life, keeping the cats engaged without needing constant replacement.
- Health and Safety Focus: The updated protocol prioritised the health and safety of the animals by minimising exposure to dirt, bacteria, and potential hazards like broken toy parts. Regular cleaning and monitoring helped prevent skin infections and digestive issues from swallowing damaged toy parts and reduced the likelihood of disease transmission, especially in a shelter environment where animals share spaces and toys.
Outcome:
- Improved Animal Health: The cleaning and replacement routine reduced incidents of skin irritations and other health concerns that had been attributed to dirty or damaged toys. The animals’ overall health improved, particularly for those with sensitive skin or immune systems.
- Increased Engagement and Interest: By regularly rotating and replacing toys, the staff saw a marked improvement in the animals’ engagement with their environment. Dogs, cats, and small animals responded with renewed enthusiasm to enrichment items that were kept clean, intact, and novel.
- Enhanced Safety: With staff trained to monitor wear and tear, the risk of choking or injury from damaged toys was significantly reduced. This ensured that enrichment time remained fun and safe for all animals involved.
- Better Shelter Environment: A cleaner, well-maintained environment not only benefited the animals but also made a positive impression on potential adopters. Happy, healthy animals in a clean space were more likely to find homes, and the shelter’s reputation for maintaining high hygiene standards contributed to this success.
Watch
When an enrichment strategy program has been implemented, it is important to observe any responses to the strategy and record and report those observations.
The reason is so that any alteration in the animal's behaviour may be recorded, and the source or reason for the response be noted. Once this has been recorded and reported, a revised strategy may be needed, especially if the response is a negative one and the response is undesirable behaviour. Then, a new or revised strategy can be implemented.
Any suggestion that you may have regarding the modification of the enrichment program must be implemented and reviewed in consultation with your supervisor, manager and /or veterinarian. Any implemented modifications and reviews must be documented as per your facility's policies and procedures.
Formats for documenting short-term and long-term enrichment strategies
The format you use to document enrichment strategies will vary depending on your workplace. It may be:
- Written on a board located with the animal
- Documented in the animal’s chart
- Documented in the animals’ notes
Check your workplace policies and procedures to ensure you know the format used for the animals’ notes.
Case Study
At Happy Paws Animal Care, the staff are committed to providing high-quality enrichment to improve the mental and physical well-being of the animals in their care. To ensure that the enrichment strategies are effective, the team regularly observes and records the animals' responses to various enrichment activities. This case study explores how the staff assessed and adjusted enrichment for both dogs and cats based on their observed behaviour and responses.
Happy Paws offers different types of enrichment programs to cater to the needs of various animals. These include:
- Puzzle feeders and treat-dispensing toys for mental stimulation
- Interactive play sessions with staff or volunteers for social enrichment
- Scent-based activities like hidden treats or toys infused with natural scents (catnip, essential oils) engage the animals' senses
- Agility courses for dogs to encourage physical activity and mental engagement
- Climbing structures and perches for cats to explore and satisfy their natural instincts
However, not all enrichment activities are equally effective for every animal, and the staff at Happy Paws recognised the importance of observing individual responses to ensure the program benefits each animal.
| Scenario: Observing Dogs’ Responses to Puzzle Feeders Case Study - Dog: Charlie (Border Collie Mix) |
Scenario: Observing Cats’ Responses to Scent Enrichment Case Study - Cat: Luna (Domestic Short Hair) |
|---|---|
|
Charlie, a high-energy Border Collie mix, had been at Happy Paws for several months. As a breed known for intelligence and physical energy, Charlie was often restless in his kennel, barking and pacing. To help relieve his boredom, the staff introduced a puzzle feeder that dispensed treats when manipulated correctly. Initially, Charlie was highly engaged with the puzzle feeder. He spent a significant amount of time interacting with the toy, showing enthusiasm and focus as he worked to retrieve the treats. However, after a week of observation, the staff noticed that Charlie lost interest in the puzzle feeder. He would attempt it for a few minutes and then abandon it, pacing and barking instead. Upon reviewing the staff notes, they realised that the puzzle feeder had become too predictable for Charlie, and he needed a greater challenge to remain mentally stimulated. Observation Outcome: Initial Engagement: Charlie engaged enthusiastically with the puzzle feeder for the first few days, solving it quickly and showing signs of mental stimulation and calmness afterwards. Adjustment Based on Observation: To address this, the team switched to a more complex puzzle feeder that required multiple steps to release the treats, providing a new challenge for Charlie. Additionally, they began rotating different enrichment activities, introducing scent-based games and interactive play sessions to maintain his interest. |
Luna, a shy domestic short-haired cat, had been showing signs of stress after being in the shelter for several weeks. She often hid in her kennel, avoiding interaction with people and other cats. To help Luna feel more secure and to reduce her stress, the staff introduced scent-based enrichment. They placed catnip toys in her enclosure and used calming lavender-infused bedding. The staff closely observed Luna’s reactions. Initially, Luna was hesitant but soon began interacting with the catnip toys, batting them around and rubbing her face on them. The staff noticed she became more active and playful. She also seemed calmer when lying on the lavender-scented bedding. However, over the course of a week, Luna’s interest in the catnip toys waned, and she returned to hiding in her kennel. Observation Outcome: Positive Response to Scent: Luna initially responded well to the catnip toys and showed increased playfulness and engagement. Adjustment Based on Observation: The staff decided to rotate the enrichment items to maintain Luna’s interest. They introduced new toys with different textures and scents, including valerian root, which some cats respond to. Luna was also given a higher perch in her enclosure to help her feel safer while observing her surroundings. These adjustments encouraged Luna to engage more with her environment while still feeling secure. |
General Findings from Observation:
- Individual Preferences:
- The observation process highlighted that each animal has unique preferences when it comes to enrichment. Some animals may prefer mentally stimulating activities (e.g., puzzle feeders), while others respond better to sensory enrichment (e.g., scent-based or tactile items). Staff found it crucial to tailor enrichment strategies based on individual behaviours and preferences.
- Adaptation Over Time:
- Through regular observation, the team at Happy Paws learned that animals could quickly lose interest in enrichment items or activities if they are not varied. Animals such as Charlie and Luna benefitted from regularly rotating enrichment activities to keep them engaged. As a result, the team developed a schedule to frequently change enrichment strategies and items to prevent habituation.
- Stress Reduction:
- For animals like Luna, who initially struggled with stress, enrichment strategies like scent-based toys and secure spaces helped to gradually reduce anxiety. Observing changes in behaviour, such as increased exploratory behaviours or reduced signs of stress (e.g., less hiding), allowed the staff to determine which enrichment strategies effectively improved the animals’ mental well-being.
Staff Actions:
- Behavioural Monitoring:
- The staff kept detailed records of each animal’s interactions with their enrichment items. They observed body language, playfulness, energy levels, and any signs of stress or frustration to understand how the animals responded to the activities.
- Adjustments Based on Behaviour:
- Enrichment activities were adapted based on observed responses. For animals that lost interest quickly, such as Charlie and Luna, the staff introduced more challenging or novel items. For animals showing signs of stress, such as hiding or retreating, they introduced calming enrichment, like scent or low-energy activities, to reduce anxiety.
- Continual Review:
- Regular review meetings were held to discuss the animals’ responses to enrichment and to update the enrichment plan accordingly. This ensured that enrichment remained engaging, stimulating, and supportive of the animals’ physical and mental well-being.
Watch
Reviewing and modifying enrichment strategies is an essential process to ensure that the activities and items provided continue to be effective, safe, and beneficial for the animals. It involves assessing current enrichment practices, identifying areas for improvement, and making necessary adjustments to meet the evolving needs of the animals. Here’s a guide on how to effectively review and modify enrichment strategies:
Regular Observation and Monitoring
- Observe Animal Behaviour: Monitor how animals interact with enrichment items and activities. Look for signs of engagement, enjoyment, or boredom. Pay attention to changes in behaviour, such as aggression, stress, or disinterest.
- Track Positive and Negative Reactions: Record whether the enrichment promotes positive behaviours, like foraging, play, and social interaction, or if it is causing negative behaviours, such as frustration, anxiety, or injury.
Assess the Effectiveness of Enrichment
- Measure Engagement: Evaluate how often animals interact with the enrichment. If an animal consistently ignores certain enrichment items, it may be a sign that the activity is no longer engaging or appropriate.
- Behavioural Improvement: Determine if the enrichment achieves its intended goals, such as reducing boredom, preventing stereotypic behaviours (e.g., pacing, overgrooming), or promoting natural behaviours (e.g., hunting, foraging, social bonding).
- Monitor Physical and Mental Health: Assess whether the enrichment supports the animal’s overall health. Animals that are physically active, mentally stimulated, and exhibit natural behaviours will likely benefit from the enrichment.
Review Safety and Health Impacts
- Check for Safety Hazards: Inspect enrichment items regularly for wear and tear, broken parts, or sharp edges that could pose a risk to the animals. Modify or replace unsafe items to prevent injuries.
- Review Dietary Impact: If food-based enrichment is used, assess whether it contributes to overfeeding, nutritional imbalances, or other health issues like obesity. Modify feeding schedules or replace treats with healthier alternatives if necessary.
- Address Potential Stress or Anxiety: Evaluate whether any enrichment activities are causing unnecessary stress or anxiety for the animals. For example, activities that involve loud noises or high-energy environments may need to be modified for more sensitive animals.
Individualise Enrichment Strategies
- Consider Individual Needs: Animals have different personalities, preferences, and health conditions. Modify enrichment programs to better suit the specific needs of individual animals, especially those with unique requirements, such as older animals, animals with disabilities, or animals recovering from illness or injury.
- Adapt Based on Age or Life Stage: Young animals may require more physically demanding or mentally stimulating enrichment, while older animals may benefit from more gentle, soothing activities. Adjust enrichment strategies based on the animal’s life stage.
Vary and Rotate Enrichment Items
- Avoid Habituation: Animals can become bored with the same enrichment activities over time, leading to a decline in their effectiveness. Regularly rotate or introduce new items and activities to keep enrichment fresh and engaging.
- Provide Variety: Offer a wide range of enrichment types, such as sensory enrichment (e.g., scent trails for dogs), physical enrichment (e.g., climbing structures for cats), cognitive enrichment (e.g., puzzle feeders), and social enrichment (e.g., group play).
- Seasonal and Environmental Changes: Modify enrichment based on changes in the environment or seasons. For example, in warmer weather, aquatic animals may enjoy frozen food or ice cubes, while in colder months, more bedding or heat sources may be required for warmth and comfort.
Get Feedback from Caretakers and Trainers
- Consult Staff: Caretakers, trainers, and handlers who work closely with the animals often have valuable insights into how well the enrichment works. Collect feedback on how animals respond to specific activities and any concerns about safety, behaviour, or health.
- Involve Veterinarians: Consult with veterinarians to ensure that the enrichment strategies align with the animal’s health and welfare needs, particularly for animals with medical conditions that require special attention.
Document and Evaluate Outcomes
- Keep Records: Maintain detailed records of enrichment activities, including the type of enrichment used, how often it’s provided, and how the animals respond. This documentation will help identify patterns and inform future decisions about modifications.
- Evaluate Behavioural Data: Use the collected data to evaluate the overall impact of enrichment strategies. If certain activities consistently lead to positive outcomes, they can be expanded, while less effective ones can be discontinued or modified.
- Use Data for Continuous Improvement: Regularly review the documented results to refine the enrichment plan, ensuring that it remains dynamic and responsive to the changing needs of the animals.
Incorporate New Research and Innovations
- Stay Updated: Enrichment practices evolve with new research and innovations in animal behaviour and welfare. Stay informed about the latest developments and best practices in enrichment for different species.
- Test New Strategies: Don’t be afraid to experiment with new enrichment ideas or products that have been shown to improve animal well-being. Always introduce new items gradually and monitor the animals’ responses closely.
- Learn from Other Facilities: Exchange ideas and enrichment strategies with other animal care facilities, sanctuaries, or zoos. Sharing knowledge can lead to new enrichment ideas or improvements to existing programs.
Modify Strategies for Special Cases
- Animals in Recovery: Animals recovering from illness, surgery, or injury may require modified enrichment that is less physically demanding but still mentally stimulating. For example, scent-based or sensory enrichment may be more suitable for a recovering animal than physical exercise.
- Animals with Behavioural Issues: Animals displaying aggressive or anxious behaviour may need different types of enrichment that focus on calming and reducing stress rather than stimulating activities. Modify enrichment to focus on relaxation, such as providing quiet, secluded spaces or sensory stimulation like soothing sounds or scents.
Regularly Schedule Reviews
- Establish Review Timelines: Schedule regular reviews of the enrichment program, such as quarterly or bi-annually, to ensure it remains effective and relevant. This process can help catch issues early and keep the enrichment program dynamic and evolving.
- Revise Based on Changes in Group Dynamics: In facilities where animals are housed in groups, changes in group composition, such as new animals or social hierarchy shifts, may require enrichment adjustments to maintain harmony and avoid competition.
As part of your duties, you may notice that there needs to be a change to the enrichment program; it is important that you notify the appropriate person and take notes of your suggestions regarding those changes. Your suggestions for program modification may include:
- Changing diet
- Changing group dynamics by adding or removing other animals
- Consultation with a behavioural specialist
- Consultation with a veterinarian on the use of chemical therapy to assist an animal's ability to deal with a stressful situation
- Further education of owner or handler:
- To control their own responses to animal behaviour
- To identify triggers in animal behaviour
- To provide more effective leadership
- Increasing or decreasing the amount and timing of stimulation offered to animal
- Providing different forms of enrichment
- Re-locate animal to a more suitable environment
Once you have permission to modify the enrichment program, you must implement these to document the final outcomes of enrichment activities.
For example, when working in any industry, you will come across policies and procedures to help you understand your role, specific work tasks, requirements of your role, and what you need to do.
Policies and procedures are critical elements in any organization, ensuring that tasks are carried out consistently, safely, and effectively. Here's an explanation of each and why they are important:
Policies
A policy is a guiding principle or rule established by an organisation to dictate what should be done in various situations. It outlines the "what" and "why" of an organisation's actions and serves as a reference point for decision-making. Policies ensure that the overall vision, values, and objectives of the organisation are upheld.
Procedures
A procedure is a detailed set of instructions that explain how to carry out tasks or processes to comply with the policies. Procedures provide the "step-by-step" actions needed to achieve a specific goal, ensuring that the task is completed correctly and efficiently.
Why Are Policies and Procedures Important Together?
When policies and procedures work hand-in-hand:
- They provide a structure that promotes smooth operations.
- They ensure legal compliance and promote workplace safety.
- They create a predictable, secure, and transparent work environment.
- They empower employees to perform their duties clearly and confidently, knowing exactly what is expected of them.
In regards to this module, we are looking at enrichment programs. Below is an example from Happy Paws Animal Care Policy and Procedure regarding enrichment. This is to help you get an understanding of what this looks like.

Happy Paws Animal Care: Enrichment Programs Policy and Procedure
Policy Statement
Happy Paws Animal Care is committed to enhancing the physical, mental, and emotional well-being of all animals in our care through well-planned and tailored enrichment programs. These programs aim to promote natural behaviours, reduce stress, and increase the overall quality of life for animals of all ages and species. Enrichment strategies will be customised based on individual needs, species, age, and developmental milestones.
Scope
This policy applies to all staff, volunteers, and caretakers at Happy Paws Animal Care who are responsible for the welfare and care of animals. It covers the process of planning, implementing, and evaluating enrichment activities for various types of animals and across their life stages.
Procedure for Creating and Providing Enrichment Programs
- Assessment of Animal Needs
- Each animal’s needs will be evaluated to determine the appropriate enrichment strategies. Factors to consider include:
- Species-Specific Behaviours: Natural instincts, such as foraging, hunting, climbing, or social interaction.
- Age and Life Stage: Young, adult, senior animals, and special milestones like juvenile development or geriatric care.
- Health and Mobility: Consider physical capabilities and any health restrictions.
- Personality and Preferences: Some animals may prefer social interaction, while others may engage better with solitary activities.
- Each animal’s needs will be evaluated to determine the appropriate enrichment strategies. Factors to consider include:
- Developing Enrichment Plans
- An enrichment plan will be created for each individual or group of animals based on their species, age, and specific needs. The plan will include:
- Types of Enrichment: Physical, mental, social, and sensory activities.
- Frequency and Duration: How often will the enrichment activities be provided and for how long will they be?
- Goals: Desired outcomes for the animal’s physical and emotional well-being.
- Monitoring and Evaluation: Regular assessments of the animal’s response to the enrichment.
- An enrichment plan will be created for each individual or group of animals based on their species, age, and specific needs. The plan will include:
- Implementation
- The enrichment activities will be implemented by staff and volunteers, with the following considerations:
- Safety First: Ensure all enrichment tools, toys, and objects are safe for the animal’s size, species, and health.
- Variety and Rotation: Regularly rotate activities and toys to prevent boredom and keep the animals engaged.
- Environmental Enrichment: Modifications to the living environment that encourage exploration, play, and natural behaviours.
- The enrichment activities will be implemented by staff and volunteers, with the following considerations:
- Documentation and Record-Keeping
- All enrichment activities must be documented to track the animal’s participation and progress:
- Date and Time: When the enrichment activity was provided.
- Activity Description: Details of the enrichment activity.
- Animal Response: Behavioural observations during and after the activity.
- Adjustments Needed: Any modifications required for future activities.
- All enrichment activities must be documented to track the animal’s participation and progress:
Enrichment Outlines by Animal Type and Age/Milestone
- Dogs

- Seniors (15+ years): Light exercise, comfortable stabling, and gentle handling to reduce stress on joints and muscles.
Review and Evaluation
All enrichment programs will be regularly reviewed by staff to ensure their effectiveness in meeting the animals’ needs. Adjustments will be made based on observed behaviours and feedback. Additionally, enrichment programs will be reassessed during key milestones or changes in an animal’s health or environment.
Industry terminology refers to the specific words, phrases, and expressions that are commonly used within a particular field or industry. These terms are often technical or unique to the industry, allowing professionals within the field to communicate more effectively and precisely.
In the table below are some industry terms you may come across/ need to use and their meaning:
| Environmental Enrichment | Modification of an animal’s surroundings to provide sensory and mental stimulation, promoting natural behaviours and improving well-being. This can include adding climbing structures, hiding spots, or objects to encourage exploration. |
| Cognitive Enrichment | Activities or tools that challenge an animal’s mental abilities and problem-solving skills. Examples include puzzle feeders or training sessions that require the animal to think and learn. |
| Sensory Enrichment | Stimulation of an animal’s senses—sight, smell, sound, taste, and touch. This might include using scent trails, introducing new sounds, or providing novel environmental textures. |
| Physical Enrichment | Activities or equipment that encourage physical activity and movement, such as exercise, climbing structures, or toys that require the animal to run, jump, or play. |
| Social Enrichment | Interactions that promote social behaviour, either with other animals of the same species or with humans. This can include playtime with conspecifics (animals of the same species) or structured time with caregivers. |
| Feeding Enrichment | Providing food in a way that encourages natural foraging or hunting behaviours. This could involve using puzzle feeders, scatter feeding, or placing food in hidden locations. |
| Tactile Enrichment | Activities or materials that stimulate the sense of touch, such as different types of bedding, textured objects, or items animals can manipulate with their paws, claws, or mouths. |
| Foraging Behaviour | The natural behaviour of searching for and obtaining food. Enrichment programs often try to replicate this behaviour by making animals work for their food using puzzles or scattering food in the environment. |
| Habituation | The process by which an animal becomes accustomed to a stimulus after repeated exposure, leading to decreased responsiveness. Habituation is considered in enrichment programs to ensure animals remain engaged and do not lose interest. |
| Stereotypic Behaviour | Repetitive, unvarying behaviours with no apparent goal or function are often seen in animals under stress or lacking stimulation. Enrichment programs aim to reduce stereotypic behaviour by providing mental and physical challenges. |
| Novelty | The introduction of new or unfamiliar objects, activities, or environments to stimulate curiosity and engagement in animals. Novelty in enrichment helps prevent boredom and encourages exploration. |
| Operant Conditioning | A type of learning where an animal’s behaviour is shaped by positive reinforcement or punishment. Used in enrichment programs for training and encouraging desirable behaviours, such as using treat rewards for task completion. |
| Species-Specific Behaviour | Natural behaviours that are typical of a particular species. Enrichment programs aim to encourage these behaviours to improve the animal's well-being and reduce stress. |
| Thermal Gradient | A range of temperatures within an animal’s environment allows them to regulate their body temperature by moving between warmer and cooler areas. Often used in reptile enrichment. |
| Behavioural Observation | The process of systematically watching and recording an animal’s behaviour in response to enrichment activities to assess its well-being and the effectiveness of the enrichment. |
|
Sensory-Motor Stimulation |
Activities that engage both sensory and motor skills, such as manipulating objects or interacting with complex environments. This type of enrichment encourages both physical and cognitive development. |
| Enrichment Schedule | A planned and documented timeline of when and how specific enrichment activities will be introduced to animals. This ensures a consistent and varied enrichment program. |
| Positive Reinforcement | Rewarding an animal for performing a desired behaviour is often used in training sessions within enrichment programs to encourage continued engagement and learning. |
| Interactive Enrichment | Activities where animals actively participate with toys, objects, or caregivers, often requiring problem-solving or physical manipulation of items to receive a reward. |
| Boredom Behaviours | Behaviours indicating a lack of stimulation, such as lethargy and excessive grooming. |
Measurement and data are essential components in various industries and fields, including animal care, as they provide the foundation for making informed decisions, ensuring efficiency, and maintaining high standards. Here’s an explanation of their importance:
Measurement is the process of quantifying or assessing something using standard units or criteria. It involves collecting specific information such as time, weight, temperature, or size to evaluate performance, progress, or conditions.
Data refers to the information collected through observation, measurement, or research. It can be qualitative (descriptive) or quantitative (numerical). In animal care, data might include health records, behaviour observations, feeding habits, or environmental conditions.
In animal enrichment programs, understanding various measurements such as volume, weight, area, ratio, and time helps design and assess activities effectively. Below are examples of how these calculations might be applied. In animal enrichment programs, understanding various measurements such as volume, weight, area, ratio, and time helps design and assess activities effectively.
Below are examples of how these calculations might be applied.
Volume
Application: Volume is important when preparing food-based enrichment (e.g., filling puzzle feeders) or when creating environmental changes (e.g., adding water to a habitat).
Example Calculation: If you need to fill a toy with 500 mL of water or food, and the toy holds 300 mL, you’ll need to refill the toy multiple times.
The formula for volume of a rectangular habitat enrichment object:
Example: If an object is 20 cm long, 10 cm wide, and 15 cm high:
Weight
Application: Measuring the weight of food or toys used in enrichment ensures appropriate portions are provided. This is also important for weight-based tasks like carrying or moving objects in physical enrichment.
Example Calculation: If a dog is fed 500 grams of food per day and the food puzzle is designed to hold 200 grams, you can calculate how much food needs to be added to ensure the dog’s daily nutritional needs are met.
The formula for weight calculation:
Example: If a bird toy weighs 100 grams and you are introducing 3 new toys:
Area
Application: Calculating the area of an enclosure or enrichment zone is essential for ensuring animals have adequate space to move around. This is especially useful when creating activity zones or placing toys and objects.
Example Calculation: Calculate the floor area for a cat enclosure if it is 3 meters by 2 meters.
The formula for area of a rectangular space:
Example: If the enclosure is 3 meters long and 2 meters wide:
You can then determine how much of the area should be dedicated to enrichment objects.
Ratio
Application: Ratios can be used to balance quantities of food or treats provided during enrichment relative to an animal’s size or daily dietary requirements.
Example Calculation: If a dog’s daily diet requires 400 grams of dry food and 1/4 of the food is to be used in a puzzle feeder, the ratio of puzzle feeder food to total food is 1:4.
The formula for ratio:
Example: If 100 grams of food goes into the puzzle feeder, and 400 grams is the total diet:
Time
Application: Timing is essential for scheduling enrichment activities and observing how long animals engage with the provided enrichment tools. You may want to ensure that each enrichment activity fits into the daily schedule or lasts for an appropriate duration to maintain engagement.
Example Calculation: If a bird engages with a puzzle feeder for 15 minutes and you aim to increase this to 30 minutes, calculate the additional time needed or adjust the complexity of the enrichment.
The formula for time:
Example: If the current engagement lasts 15 minutes and you want it to last 30 minutes:
Case Study
Using Data and Information to Inform Enrichment Programs in Animal Care
Scenario
Sarah is an animal care worker at Happy Paws Animal Care. Her role includes creating, implementing, and evaluating enrichment programs for the animals in her care, including a group of adult dogs, birds, and reptiles. To ensure the animals receive appropriate physical and mental stimulation, Sarah relies on key calculations like volume, weight, area, ratio, and time to tailor enrichment activities effectively. Here’s how she applies these data points in her daily tasks.
Calculating Volume for Food-Based Enrichment (Dogs)Task: Sarah is preparing a food puzzle for the dogs using Kongs filled with wet food. Each dog requires 400 grams of food per day, but she wants to use the Kongs to provide a portion of their meal in an enriching way. The Kong holds a volume of 300 mL, and Sarah plans to split the dogs’ meals between the Kongs and regular bowls.
This ensures the dogs receive both proper nutrition and a mentally stimulating activity without exceeding their daily food intake. |
Weighing Enrichment Tools (Birds)Task: Sarah is enriching the birds’ environment by introducing new hanging toys that encourage foraging and climbing. However, some birds are small, and the toys should not be too heavy. She selects toys that weigh 50 grams each but needs to ensure the total weight is safe for the birds’ perches.
|
Measuring Area for Reptile EnclosuresTask: Sarah must redesign the snake enclosures to incorporate new enrichment objects like climbing branches and hides. The enclosure measures 120 cm long, 60 cm wide, and 50 cm high. She must ensure the new enrichment doesn’t overcrowd the space, allowing the snake to move freely.
|
Using Ratios for Balanced Enrichment (Dogs)Task: Sarah provides food-based enrichment for the dogs, using 1/4 of their daily meal in a puzzle feeder. The dogs require 400 grams of food per day. Sarah needs to ensure the ratio of food given in the puzzle feeders doesn’t exceed this.
|
Timing Enrichment Activities (Birds and Reptiles)Task: Sarah wants to track how long the birds and reptiles engage with their enrichment activities. She is particularly interested in increasing the time spent on foraging puzzles for the birds and scent trails for the reptiles.
|
Conclusion
By using data on volume, weight, area, ratio, and time, Sarah ensures that enrichment activities at Happy Paws are safe, stimulating, and tailored to the specific needs of each animal. These calculations help her make informed decisions, track progress, and adjust the programs. The documentation of these activities also provides a clear record, ensuring consistency and continual improvement of the animal's care and well-being.
