Mustelids including ferrets, mink, otters, and martens are highly active, intelligent carnivores with complex behavioral needs. Captive management of these species requires understanding their demanding welfare requirements.
Mustelid welfare in captivity is consistently challenging because these are highly active, intelligent, space-demanding animals whose natural behavioral repertoire requires more than most captive environments can provide. Ferrets as pets are chronically under-exercised in small cages, developing adrenal disease partly as a consequence of inappropriate light cycles and inactivity. Mink on fur farms are among the most thoroughly documented cases of chronic welfare compromise in captive animals - a fact that has driven fur farming bans across much of Europe. Wild mustelid species in rehabilitation need extensive and expensive facilities to recover adequately. Any commitment to mustelid welfare requires understanding and meeting the high behavioral and spatial requirements of these energetic carnivores.
