Enrichment Devices for Nonhuman Primates


There has been in recent years a substantial increase in the variety of enhancement devices available for nonhuman primates in captivity, and the task of properly outfitting a housing unit can be daunting. Researchers continue to investigate the specific impact and importance of environmental enrichment, but it is generally accepted that increasing the complexity of the environment for the mental and physical stimulation of nonhuman primates is beneficial to their health and contentment, and enrichment is now a standard component of primate husbandry.
