Ferret Care Basics

Are ferrets legal to keep, and what housing do they need?

Ferret ownership is regulated differently from place to place, and ferrets should only be kept where legal in your state; local and state regulations should be confirmed before acquiring one. Where permitted, ferrets are notorious escape artists and need secure, ferret-proofed housing — cages with small enough bar spacing, latches that a ferret cannot manipulate, and a ferret-proofed room for supervised free time, since ferrets can squeeze through surprisingly small gaps and will investigate and chew on soft rubber and foam items, which can cause a life-threatening intestinal obstruction if swallowed.

What should ferrets eat?

Ferrets are obligate carnivores with a short digestive tract and high protein and fat requirements. A high-quality diet formulated specifically for ferrets, made primarily from animal protein rather than grain or plant-based fillers, is the appropriate diet base. Ferrets are prone to selectively eating around a poor-quality diet, so diet quality matters more for ferrets than for many other companion animals.

What vaccinations do ferrets need?

Ferrets are susceptible to canine distemper virus, which is fatal in ferrets, and vaccination against distemper is a core part of preventive care. Rabies vaccination is also recommended and may be required depending on local regulations. A veterinarian familiar with ferrets can advise on an appropriate vaccination schedule.

What health problems commonly develop in middle age?

Adrenal disease is common in ferrets from early middle age onward, with signs that often include hair loss (particularly starting at the tail and spreading forward), itchy skin, and behavioral changes. Insulinoma, a tumor of the insulin-producing cells of the pancreas, is also common and causes episodes of weakness, lethargy, drooling, or collapse related to low blood sugar. Both conditions are manageable when caught early, which is one reason regular veterinary attention matters as ferrets age.

Why do annual exams matter?

Because ferrets age quickly and can develop adrenal disease, insulinoma, and other conditions as early as three to four years of age, annual wellness exams — and twice-yearly visits for ferrets over three — allow these problems to be identified while still manageable. Routine bloodwork and a hands-on exam are typically part of these visits.
