Chimpanzees are our closest living relatives and share complex emotional and social lives. Their welfare in captivity demands large social groups, rich environments, and expert care.
Chimpanzee welfare requires exceptional investment in social group management, environmental complexity, and cognitive enrichment. Solitary or pair-housed chimps develop severe psychological disorders — self-mutilation, stereotypies, and depression are documented in inadequately housed individuals. Large groups with complex social structures, hierarchy negotiation, and social play opportunities are fundamental requirements. Enclosures must provide climbing structures of appropriate scale, diverse substrates, and separation of social spaces. Cognitive enrichment — tool use, puzzle feeders, novel problems — addresses the intellectual needs of an animal with demonstrated problem-solving and planning abilities. Chimpanzee sanctuaries in Africa housing orphans from the bushmeat and pet trades demonstrate that rescued animals can recover and form functional social groups with appropriate long-term support.
