Ferrets are legal to own as pets in 48 out of 50 U.S. states. California and Hawaii are the only two states with outright bans, and a handful of cities, most notably New York City and Washington, D.C., prohibit them as well. If you live outside those areas, you can likely bring a ferret home, though local rules on permits, vaccinations, and housing vary.
States Where Ferrets Are Banned
California has banned pet ferrets since 1933, primarily because escaped ferrets are effective predators that could devastate native wildlife. Hawaii’s ban exists for a different reason: it is the only U.S. state free of the rabies virus, and ferrets can carry rabies. In both states, it is illegal to buy, sell, adopt, or even bring a ferret with you if you move there from another state.
In the remaining 48 states, ferret ownership is legal at the state level. However, some states require a rabies vaccination certificate or a health certificate from a veterinarian before purchase or transport. Requirements vary, so checking with your state’s department of agriculture before buying is a smart move.
Cities and Counties With Local Bans
Even in states where ferrets are legal, certain cities and counties have their own prohibitions. The two most significant are New York City and Washington, D.C. In New York City, ferrets were added to the Health Code’s list of presumptively wild animals in 1999, and a state Supreme Court judge later upheld the ban. That means ferrets are perfectly legal in the rest of New York State but not within the five boroughs. Washington, D.C., also bans private ferret ownership.
Smaller municipalities occasionally have restrictions too. Before committing, check your city or county’s animal control ordinances. A quick call to your local animal control office can confirm whether any local rules apply.
Ferret Laws Outside the United States
The United Kingdom allows ferret ownership with no special permit. Owners are expected to meet general animal welfare standards, including providing proper housing, diet, and veterinary care. Ferrets are a common pet there, with a long cultural history tied to hunting.
Australia presents a mixed picture. Around 150,000 ferrets are kept as pets across the country, but Queensland and the Northern Territory classify ferrets as prohibited invasive animals under biosecurity law. In those regions, you cannot keep, move, sell, or give away a ferret, and penalties apply. Other Australian states and territories permit ownership.
Countries like Japan, Brazil, and parts of Southeast Asia have varying rules. Some require import permits, others ban ferrets entirely. If you’re outside the U.S. or U.K., your national or regional wildlife authority is the best source for current regulations.
Vaccinations and Legal Requirements
In most U.S. jurisdictions where ferrets are legal, annual vaccinations against rabies and canine distemper are either required or strongly recommended. Only one rabies vaccine is approved for ferrets in the United States, and it should first be given at 16 weeks of age, then repeated every year. Kits (baby ferrets) and adults with no vaccination history need a series of distemper boosters.
Some cities and counties require proof of current rabies vaccination to license a ferret, similar to dog licensing. Keeping your vaccination records organized is important, especially if you travel across state lines with your pet.
What Ferret Ownership Actually Costs
The upfront investment is moderate. Adopting from a shelter typically runs $0 to $300, while buying from a breeder costs $275 to $400. A sturdy, multi-level wire cage adds $100 to $250. Bedding, litter pans, food bowls, water bottles, hammocks, toys, tunnels, a carrier, and grooming supplies bring the initial setup to roughly $100 to $270 on top of the cage.
Ongoing costs add up faster than many new owners expect. High-quality kibble runs $10 to $15 per month, and litter and bedding cost another $5 to $10 monthly. Annual vet visits with rabies and distemper vaccines typically cost $150 to $200 per ferret. Ferrets are prone to adrenal disease as they age, and treatment for that can add $200 or more per year. All in, expect to spend roughly $330 to $700 annually per ferret on food, supplies, and veterinary care.
Finding a Ferret to Adopt
Ferret-specific rescue organizations exist in most regions of the country. The American Ferret Association maintains a shelter directory listing rescues in states from Alabama to Indiana to Massachusetts and beyond. Many of these shelters hold 501(c)(3) nonprofit status, and adoption fees are generally lower than breeder prices. Rescues also tend to provide ferrets that are already spayed or neutered and up to date on vaccinations.
Pet stores are another source, though the animals typically come from large breeding operations. If you go this route, ask for health records and check the ferret’s alertness, coat condition, and energy level before purchasing. A lethargic or thin ferret may already have health problems.
Finding a Vet Who Treats Ferrets
Not every veterinary clinic treats ferrets. They are classified as exotic mammals, and their medical needs, from diet to disease management, require specialized training. The Association of Exotic Mammal Veterinarians offers a “Find a Vet” tool on its website that lets you search for veterinarians near you with specific experience in exotic mammal care. Identifying a vet before you bring your ferret home is essential, since ferrets need their first wellness visit and vaccinations early on.
Ferret-Proofing Your Home
Ferrets are curious, flexible, and surprisingly good climbers. They can squeeze through gaps in doors, slip behind appliances, and chew on soft or spongy objects that cause intestinal blockages. Before letting a ferret roam, you need to address several categories of household hazards.
Structural risks include open doors and windows, gaps under cabinets, open railings on stairs or balconies, and air conditioning ducts. Ferrets will explore all of these. Appliances like washers, dryers, stoves, and refrigerators have warm, dark spaces that attract ferrets, so always check before turning them on.
Ingestion hazards are a serious concern. Balloons, erasers, foam, rubber bands, buttons, and sponges are all dangerous if swallowed. Keep these off the floor and out of reach. Houseplants, cleaning chemicals, rodent baits, and medications (both human and pet) should be stored in locked or secured cabinets. Ferrets are resourceful enough to open garbage containers, so those need to be secured as well.
Water poses a drowning risk. Keep toilet lids closed, empty sinks and bathtubs, and supervise any access to pools. Temperature matters too. Ferrets are highly susceptible to heat stress at temperatures above roughly 77°F to 86°F (25°C to 30°C), so air conditioning or cool shelter is necessary in warm climates. Finally, supervise interactions with children and other pets until you’re confident everyone is safe together.
