Wolverines are wide-ranging, solitary mustelids that present significant welfare challenges in captivity. Understanding their needs helps evaluate zoo care standards for this demanding species.
Wolverines represent an extreme case in zoo animal welfare. Their natural history — vast solitary ranges, secretive behavior, cold adaptation, and wide-ranging movement — is fundamentally incompatible with zoo environments. The high prevalence of stereotypic pacing in captive wolverines is a clear welfare indicator of inadequate space and stimulation. Temperature management is essential for animals adapted to subarctic conditions. The conservation case for zoo wolverines is weak, and the ethical case for keeping wolverines in conditions that cannot meet their needs is correspondingly difficult to make.
