Ferrets are playful, intelligent mustelids that need complex environments and social companionship. Meeting their needs prevents the frustration and health problems common in poorly kept pets.
Ferret welfare is frequently compromised by insufficient living space, social isolation, and inadequate exercise opportunities. Small cages may be acceptable as sleeping quarters but should not confine ferrets throughout the day. Daily out-of-cage time in ferret-proofed areas allows the activity their physiology requires. Social housing with at least one companion ferret prevents isolation-related decline. Tunnel systems, hiding places, and digging boxes satisfy natural burrowing motivation. The health epidemic of adrenal disease in domestic ferrets is linked to early neutering, artificial light cycles, and processed diets — areas where welfare-conscious husbandry can make a difference over generations of domestic ferret populations.
