The 1985 amendments to the Animal Welfare Act included provisions for the promotion of the psychological well-being of nonhuman primates and for exercise for dogs. Today, many research, teaching and testing facilities have established environmental enrichment programs for all animal species.

In this section, you will find general information on enrichment for laboratory animals. Species-specific information is found by going to the various Laboratory Animal Species pages of this site. Additional resources are found in the enrichment sections for Zoo, Circus and Marine Animals and Farm Animals.
