Enrichment is a research area focused on improving the welfare and well-being of animals in captivity by providing them with stimulating and engaging environments. This can include physical, social, and cognitive forms of enrichment that encourage natural behaviors, enhance mental and physical health, and reduce stress and boredom. Enrichment practices may involve providing animals with new objects to explore, puzzles to solve, opportunities for social interaction, or activities that mimic their natural habitat. Overall, enrichment aims to enhance the quality of life for animals in captivity and promote their overall health and happiness.
