Ferrets are highly intelligent, energetic and social animals whose welfare needs are significantly underestimated by the average first-time owner.
Ferret welfare failures are almost entirely husbandry failures: inadequate diet, insufficient exercise, social isolation, and failure to spay females who will not be bred. A ferret in a small cage for most of the day, fed inappropriate food and kept alone, is experiencing multiple simultaneous welfare deficits. Their energy and curiosity — which make them entertaining — also make them utterly unsuited to sedentary existence. The health consequences of neutering (adrenal disease, insulinoma) have driven increasing interest in alternative reproductive management using implants rather than surgical neutering.
