Animals use various senses to find food, mark territories, communicate with conspecifics and many other behaviours. Providing enrichment which stimulates these different senses can help to encourage these natural behaviours. Different species will rely on certain senses more than others, so it is important to know which senses to target when providing enrichment activities to ensure that they are successful.
Focus on encouraging hunting and feeding behaviours. Think about where they would find their prey, how they would stalk, chase and catch their prey and any species-specific hunting behaviours or adaptations. Food items including fur and feathers will encourage natural feeding (and sometimes play) behaviours and increases the time taken to consume food.
