Ferrets are obligate carnivores and highly active mustelids with specific behavioral and dietary needs. Understanding these needs is essential for providing good welfare in captivity.
Ferret welfare is compromised in many captive situations by inappropriate diet, social isolation, and inadequate exercise. Dry commercial ferret kibble high in plant protein causes chronic digestive stress and may contribute to the high prevalence of insulinoma and adrenal disease in US ferrets. Social isolation in a species that naturally lives in social groups causes stress and behavioral poverty. Inadequate exercise in a species with high activity requirements leads to obesity and behavioral frustration. The very high prevalence of endocrine disease in middle-aged and older ferrets — particularly in the US where early-age neutering is standard practice — represents a population-level welfare problem that may be linked to hormone disruption. Good ferret welfare requires specific knowledge that many owners acquire only after problems emerge.
