African crested porcupines are the world's largest rodents and highly social pair-bonded animals. Zoo welfare requires nocturnal exhibit management, foraging enrichment, and stable pair or family housing.
African crested porcupine welfare in captivity depends on three key factors: pair-bond maintenance, nocturnal management, and digging opportunity. Separating bonded pairs for any reason causes profound stress — pair housing must be planned with the assumption that separations for veterinary procedures are highly aversive and should be minimised. Exhibits that force daytime activity through visitor-facing design suppress natural behaviour — porcupines should have access to dark burrow areas during the day. Foraging enrichment buried in soil or substrate engages their natural rooting behaviour; lack of digging opportunity leads to oral stereotypies and pacing. Diet should include root vegetables, tubers, and browse that require manipulation — porcupines use their forepaws and teeth to process food in ways that provide both nutritional and behavioural satisfaction. Keepers should be trained in safe porcupine handling to minimise quill injury risk during necessary veterinary procedures.
