African crested and North American porcupines have specific nocturnal and foraging welfare needs that require thoughtful enrichment and exhibit design in zoo settings.
Porcupine welfare in zoo settings benefits from recognition of their gnawing as a functional biological need, not merely a behavioral quirk. Providing hard wood for gnawing, bark-covered browse, and root vegetables engages their natural dental maintenance behavior and prevents destructive stereotypic gnawing on exhibit structures. As nocturnal animals, they benefit from reversed light cycle exhibits that allow public viewing during their natural active hours. Social management as largely solitary animals requires careful monitoring if cohoused. Regular provision of novel foraging challenges maintains behavioral diversity and prevents the monotonous gnawing patterns associated with insufficient enrichment.
