African crested porcupines are nocturnal burrowers requiring appropriate substrate, hiding structures, and respect for their defensive nature in zoo settings.
Porcupine welfare in captivity centers on providing adequate substrate for burrowing, appropriate pair or family housing, and nocturnal exhibit management that respects their activity patterns. Forcing nocturnal species into daytime visitor display denies them natural sleep patterns and creates chronic stress. Gnawing enrichment including bones, wood, and hard root vegetables satisfies dental and foraging needs. Porcupines are defensive rather than aggressive, and stress from excessive human proximity or loud noise causes them to raise quills repeatedly — a reliable indicator of poor welfare conditions.
