Ferrets are intelligent, curious, and endlessly entertaining — but they are also demanding pets that require specialist care. They are obligate carnivores with strict dietary needs, they sleep 14-18 hours per day, and they are infamous escape artists. Their healthcare needs are more complex than most small animals, with adrenal disease and insulinoma being common conditions in middle-aged ferrets.

Essential Care Overview
Housing
Ferrets need a large, multi-level cage with bar spacing ≤ 2.5cm (1″). Solid floors only — wire mesh causes bumblefoot (see our bumblefoot guide). Secure clip-locks on every door (ferrets learn to open spring latches). Multiple hammocks and dark sleeping spots are essential — ferrets sleep 14-18 hours daily.
Diet
Ferrets are strict obligate carnivores with the shortest digestive tract of any common pet. They need high-protein (34-40%), high-fat (15-20%), low-fibre (<3%) food. Raw feeding following the 80/10/10 ratio (muscle/bone/organ) is considered optimal. Never feed fruit, vegetables, or grain-based foods — ferrets cannot digest plant matter. See our food guide.
Out-of-Cage Time
Ferrets need a minimum of 4 hours out-of-cage time daily for exercise and exploration. The room must be “ferret-proofed”: block gaps behind appliances, secure vents, remove rubber/foam items (common foreign body ingestion), and supervise constantly.
Common Health Issues
- Adrenal disease: Very common in ferrets over 3 years. Symptoms: hair loss, enlarged vulva (females), aggression. Treatable with deslorelin implant.
- Insulinoma: Pancreatic tumours causing low blood sugar. Symptoms: lethargy, pawing at mouth, staring, collapse. Requires veterinary management.
- Blockages: Ferrets chew and swallow rubber, foam, and fabric. Foreign body obstruction is a common emergency.
