Zoos and other facilities that are regulated by accrediting bodies have come a long way from the bland concrete menageries that previously housed wild animals, and the standards of animal management and welfare are of a much better quality. Well-researched nutritional diets and veterinary care help to keep animals in a good physical condition, however, even the most physically healthy individual may be compromised in terms of their mental welfare, and this is where having a well-structured enrichment programme can really help. There have been lots of studies into the impact of enrichment and it is clear that it has a positive impact on both mental and physical welfare.
