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.

Recent Findings
Smithsonian's National Zoo Animals Weather Sandy
All the animals are safe and healthy! Zoo staff worked late into the cold, dark night and cleverly repurposed Boo at the Zoo decorations to prepare the Zoo for Sandy's ravages. more
Twin Fishing Cats Born at the National Zoo—a First
The Smithsonian's National Zoo is closer to cracking the code for breeding one of Asia's most elusive species with the birth of two fishing cats (Prionailurus viverrinus). Seven-year-old Electra delivered the kittens between 9 a.m. and 4 p.m. May 18 in an off-exhibit den. Their birth marks an important milestone: this is the first time fishing cats have successfully bred and produced young at the National Zoo. more
