Chimpanzees retired from biomedical research and the exotic pet trade face complex welfare challenges in sanctuary settings. Best-practice care requires understanding their trauma histories.
Chimpanzee sanctuary welfare involves addressing decades of accumulated psychological trauma. Research chimps conditioned to fearful human interactions require years of patient positive reinforcement work before they can be safely introduced to social groups. Former pets often cannot be integrated due to abnormal social development. The welfare cost of research and pet ownership extends long beyond individual life stages into lifetime rehabilitation requirements.
