Overview
Ferrets are domesticated mustelids, not rodents, and are obligate carnivores with the curiosity and athleticism of a small predator.
They sleep 14-18 hours a day but are intensely energetic when awake, often performing a bouncing "weasel war dance." They bond with people and other ferrets and learn routines and litter habits.
They suit dedicated, experienced keepers.
Their high needs, frequent veterinary issues, and musky odor make them a poor impulse purchase.
In some regions they are restricted or banned, so check local law before committing.
Housing
Provide a tall, multi-level wire cage of at least 90x60x60cm for one or two ferrets, with solid shelves, hammocks, and a litter tray.
The cage is only a base camp: ferrets need several hours of supervised free-roaming exercise every day in a thoroughly ferret-proofed room.
They are skilled escape artists who squeeze through gaps as small as 2.5cm and chew or dig at anything.
Block all holes, secure cupboards, and remove soft foam and rubber, which can cause fatal intestinal blockages.
Keep them cool; they risk heatstroke above about 28-30C.
Diet
As obligate carnivores, ferrets need a diet very high in animal protein and fat with little carbohydrate or fibre.
Feed a quality ferret kibble, or a balanced raw or whole-prey diet, with roughly 32-38% animal protein and 18-20% fat.
Avoid dog food, fruit, vegetables, and sugary treats.
Their gut transit is only about 3-4 hours, so food should be available frequently or free-fed, with constant fresh water.
Sugary or carbohydrate-heavy diets are linked to insulinoma, a common ferret cancer.
Health
Ferrets are prone to several serious conditions: adrenal gland disease, insulinoma (pancreatic tumors causing low blood sugar), lymphoma, and dental disease.
Early-neutered animals from large breeding mills are especially predisposed to adrenal disease.
Annual checks, moving to twice-yearly with age, are advised with an exotic vet.
They require core vaccination, typically against canine distemper, which is almost always fatal in ferrets, and against rabies where mandated.
Keep them away from infected dogs.
Sudden weakness, drooling, or hind-leg collapse can signal an insulinoma crisis needing urgent care.
Temperament
Ferrets are mischievous, intelligent, and affectionate, forming clear bonds with their humans and cage-mates.
They communicate with chirps, hisses, and "dooking" chuckles, and most enjoy gentle handling, tunnels, and interactive games.
Kits nip while learning bite inhibition and need patient, consistent training.
They are not ideal for very young children or hands-off owners.
Without enough stimulation they become bored, destructive, or withdrawn.
A compatible companion ferret plus rich daily enrichment keeps them mentally healthy.

Experienced, very hands-on owners
Households able to give hours of daily play
Keepers wanting a dog-like interactive small pet
Homes that can be fully escape-proofed
Common mistakes to avoid
Feeding dog food, fruit, or carbohydrate-heavy diets
