Chimpanzees retired from biomedical research require lifelong sanctuary care that addresses their complex social, cognitive, and physical needs.
Chimpanzee sanctuaries carry an unusual burden: they provide lifelong care for animals who were used in research to benefit human health, creating a moral debt that the sanctuary system attempts to honour. The welfare challenges are substantial. Chimps arriving from laboratory settings often carry the psychological legacy of years of isolation, repeated procedures, and social deprivation. Rebuilding social bonds and normal chimpanzee behaviour takes years of careful management. The physical infrastructure requirements for appropriate chimpanzee care are extensive and expensive. Funding is a persistent challenge as the costs of lifetime care for large, long-lived, cognitively complex animals are enormous. The welfare standard to which sanctuaries aspire is not merely survival but genuine flourishing: complex social lives, cognitive engagement, physical health, and positive emotional states.
