Chimpanzees rescued from research facilities, entertainment, or the pet trade require years of careful behavioral rehabilitation to recover from trauma and develop appropriate social skills.
The rehabilitation journey of research-retired chimpanzees is measured in years, not months. Animals that have lived in isolation lack the social skills to negotiate chimpanzee group dynamics, and introductions managed too quickly can result in severe injuries or death. The welfare of sanctuary chimpanzees depends on staff who understand chimpanzee social behavior, can read subtle behavioral signals, and manage group composition patiently. The investment required for lifetime high-welfare chimpanzee care is substantial but morally obligatory given the circumstances that created the need.
