Smithsonian National Zoological Park l Friends of the National Zoo



The Center for Animal Care Sciences provides science-based husbandry, medical care, and population management for the health and well-being of all animals in the National Zoo’s collection as well as for animals at other zoos and in the wild. We lead and collaborate in conservation breeding programs, wildlife husbandry and exhibitry, and public education.

Center for Animal Care Sciences (CACS) veterinarians, curators, researchers and animal care staff lead and participate in initiatives focusing on population sustainability, wildlife health and emerging diseases, nutrition, animal behavior and cognition, and captive animal management and exhibitry through enhanced enrichment and training programs. CACS leads the field in innovative, science-based approaches to the assessment of animal health and well-being both in theory and in practice.
