Wolverines are wide-ranging, solitary mustelids whose welfare in captivity requires exceptional space and enrichment to prevent the severe stereotypies documented in barren exhibits.
Wolverine welfare in captivity is exceptionally challenging because the mismatch between their natural ranging requirements and any feasible enclosure size is extreme. Even large, well-designed exhibits provide only a fraction of the territory a wild wolverine would use. Welfare-conscious facilities compensate with intensive enrichment programs: varied substrates, food caching opportunities, olfactory enrichment, and changing environmental complexity. Without this investment, wolverines default to severe stereotypic pacing. The conservation value of educating the public about wolverines must be weighed against the significant welfare compromise inherent in their captivity.
