As zoo gorillas reach advanced ages of 40-55 years, geriatric welfare requires specialized management for chronic disease, cognitive changes, and compassionate end-of-life care.
Gorilla geriatric welfare is a growing specialty as improved zoo management extends lifespans into territory where chronic disease management becomes central to daily care. Cardiac disease in male gorillas mirrors human cardiovascular disease in both pathology and treatment approach — the genetic proximity of gorillas to humans makes their cardiac vulnerabilities similar. Welfare monitoring in aging gorillas requires attention to subtle behavioral changes: reduced grooming participation, decreased social interaction, altered posture, and food selectivity all signal welfare changes that warrant veterinary assessment. Keepers who work closely with long-lived gorillas develop detailed individual behavioral knowledge that enables early identification of wellness changes. End-of-life decision-making for gorillas — animals with profound emotional lives and deep social relationships — requires particular sensitivity to quality of life.
