Wolverines are among the most wide-ranging mammals on Earth. Providing adequate welfare in captivity is exceptionally challenging and raises fundamental questions about the ethics of keeping this species in zoos.
Wolverines represent one of the most ethically challenging species for zoo keeping. Their extraordinary ranging behaviour, solitary nature, and requirement for specific thermal conditions cannot be meaningfully replicated in any zoo setting. The result is that captive wolverines almost universally exhibit high rates of stereotypic behaviour, indicating chronic frustration of natural movement drives. While the educational value of wolverine exhibits is real, this must be weighed honestly against the quality of life experienced by the animals. Zoos maintaining wolverines have a responsibility to provide the largest possible enclosures with varied terrain, temperature-controlled denning areas, complex foraging challenges, and scent enrichment across extensive areas. The question of whether welfare in captivity can ever be adequate for this species deserves transparent examination.
