Ferrets are legal to own in Michigan, but that does not mean there are no rules to follow. The state has an entire dedicated law — Act 358 of 1994 — that governs ferret ownership, breeding, importation, and what happens when something goes wrong.

Whether you already share your home with a ferret or are thinking about bringing one home, understanding Michigan’s ferret laws protects you, your pet, and the people around you. This guide walks through every layer of the law, from statewide requirements to local ordinances, so you know exactly where you stand.

Key Insight: Michigan is one of the few states with a standalone ferret statute. Most rules for pet ferrets in the state flow directly from Michigan Compiled Laws 287.891 through 287.901.

Are Ferrets Legal in Michigan?

Yes, ferrets are legal to own as pets in Michigan. Michigan is among the states where ferrets are legal but regulated, meaning ownership is permitted statewide as long as you comply with the requirements set by state law. You do not need a special permit simply to keep a ferret as a companion animal.

Michigan enacted an extensive, multi-section law upon legalization in 1994 dealing exclusively with ferrets (Act 358, MCL 287.891–287.898). That law defines who qualifies as an owner, what vaccinations are required, how breeding is regulated, and what penalties apply when the rules are broken.

Under Michigan law, “ferret” means an animal of any age of the species Mustela furo. That definition covers all domestic ferrets regardless of color, size, or age. It is worth noting that ferrets may not always be explicitly listed in regulations regarding exotic pets, and they may be regulated at the county, municipal, or local level even when they are legal at the state level. Always check with your local municipality before acquiring a ferret, even though the state permits ownership broadly.

If you are curious how ferret ownership compares to other pet regulations in the state, the general pet laws in Michigan provide a useful broader context.

Permit and Registration Requirements for Ferrets in Michigan

For most pet owners, no permit is required at the state level simply to own a ferret. However, permits and registration become relevant in two specific situations: breeding and local licensing ordinances.

Breeding Permits

A permit is required to breed ferrets in Michigan. Hobby breeders with up to four ferrets that are six months or older, or a litter under five months on a temporary basis for recreational purposes, are exempt from this permit requirement if listed criteria are met.

A hobby breeder may engage in the breeding of ferrets without a license or permit if all of the following criteria are met: ferrets are housed indoors, and the temperature is sufficiently regulated by heating or cooling to protect the ferrets from extremes of temperature, to provide for their health, and to prevent their discomfort. Additional requirements cover ventilation, lighting, cage space, food, water, and sanitation.

Local Licensing

A local unit of government by ordinance may establish licensing requirements for ferrets. The ordinance shall provide for proof of rabies vaccination, license tags, forms, and procedures as described for dogs pursuant to the dog law of 1919.

Battle Creek is one example of a Michigan city that has exercised this authority. No person shall own, harbor, or keep a ferret over twelve weeks of age within the City without first obtaining a license therefor from the City Treasurer or the authorized agent of the City Treasurer. The application for such license shall state the breed, sex, age, color and markings of such ferret, whether the ferret is spayed or neutered, or whether the animal has a microchip, and the name, address, and telephone numbers of the owner.

Within seven days of a ferret becoming 12 weeks of age, the owner shall apply for a license. The license year shall commence on the first day a license is issued and end after 365 days, or on the expiration of the rabies certificate of vaccination, whichever occurs first.

Pro Tip: Even if your city does not currently require a ferret license, contact your local animal control office to confirm. Municipalities can adopt or update ferret ordinances at any time, and requirements vary significantly across Michigan.

For a broader look at how Michigan animal laws work at the local level, see this overview of animal cruelty laws in Michigan, which also touches on enforcement structures across the state.

Vaccination and Neutering Requirements in Michigan

Michigan’s ferret statute is explicit about vaccination. A person shall not own or harbor a ferret over 12 weeks of age unless the ferret has a current vaccination against rabies with an approved rabies vaccine administered by a veterinarian, except that rabies vaccinations are not required for research ferrets kept at research facilities registered pursuant to the public health code.

This means the rabies vaccine must be administered by a licensed veterinarian — not self-administered — and must remain current throughout the ferret’s life. You will also need to be able to produce that documentation on demand. A person who owns or harbors a ferret shall produce proof of a valid rabies certificate signed by a veterinarian for the ferret upon request of a law enforcement agent or animal control officer or the director.

Importing Ferrets into Michigan

A person shall not import a ferret into this state unless the person has an official interstate health certificate or official certificate of veterinary inspection signed by an accredited veterinarian and a current rabies vaccination if the ferret is over 12 weeks of age, and a current distemper vaccination if the ferret is over 6 weeks of age.

This is an important requirement if you are purchasing a ferret from a breeder in another state or relocating to Michigan with your ferret. Both health documents must be in order before the animal crosses state lines. For more on how Michigan handles the movement of animals across its borders, see the pet import laws in Michigan.

Neutering

Michigan’s statewide ferret law does not impose a mandatory neutering requirement for pet ferrets in private ownership. However, some local ordinances do. For example, Battle Creek’s license application requires the owner to state whether the ferret is spayed or neutered. This suggests local governments track neutering status even when state law does not mandate it. If you live in a city with a ferret licensing ordinance, check whether spaying or neutering is required or affects your licensing fee.

Important Note: The approved rabies vaccine for ferrets must be specifically authorized by the Michigan state veterinarian. Not every rabies vaccine product is approved for use in ferrets. Ask your veterinarian to confirm they are using an approved product so your vaccination documentation will be valid under state law.

Local Laws That May Apply in Michigan

Even in states where ferret ownership is generally permitted, local ordinances can impose additional restrictions or outright bans. These local laws are distinct from state regulations and can significantly impact whether a ferret can be legally kept in a specific area.

In Michigan, this plays out in a few ways. Some cities have adopted licensing ordinances modeled after the state’s framework for dogs. Others may have zoning rules, housing codes, or rental agreements that restrict pet ownership more broadly. Michigan’s ferret statute explicitly preserves local authority: a local unit of government by ordinance may establish licensing requirements for ferrets, and the ordinance shall provide for proof of rabies vaccination, license tags, forms, and procedures as described for dogs pursuant to the dog law of 1919.

What to Check in Your Municipality

Whether your city or township has a ferret licensing ordinance

Whether your zoning district permits the number of animals you plan to keep

Whether your rental agreement or homeowners association rules restrict ferret ownership

Whether any breed-specific or exotic animal ordinances in your area could apply

Prospective ferret owners are encouraged to confirm legality with local authorities before adopting. A quick call to your city or township’s animal control department can save you significant trouble later. You may also find it helpful to review the kennel zoning laws in Michigan if you plan to keep multiple ferrets or engage in hobby breeding, as zoning rules can affect where and how many animals you may keep on a property.

Owners in Michigan who also keep other pets should be aware that different animals carry different local rules. For instance, hedgehog ownership laws in Michigan and goat ownership laws in Michigan each have their own distinct regulatory frameworks at the state and local level.

Ferret Care and Housing Standards in Michigan

Michigan law sets specific care and housing standards, particularly for hobby breeders. Even if you are not breeding ferrets, these standards give a good baseline for what responsible ownership looks like under state law.

Housing Requirements

Each ferret must have a minimum of 2 square feet of floor space in a well-ventilated cage. Each cage is equipped with, at a minimum, a food hopper or bowl, a water bottle, a litter box, and bedding appropriate for the season.

Temperature regulation is also required. Ferrets are housed indoors, and the temperature is sufficiently regulated by heating or cooling to protect the ferrets from extremes of temperature, to provide for their health, and to prevent their discomfort. Fresh air is provided by means of windows, doors, vents, fans, or air conditioning and shall be ventilated so as to minimize drafts, odors, and moisture condensation. Lighting by natural or artificial means is ample and of sufficient intensity to permit routine inspection and cleaning.

Food and Water Standards

The food must be wholesome and of sufficient quantity and nutritive value to maintain all ferrets in good health. Ferrets are fed at least once a day except as dictated by veterinary treatment. Food receptacles are located so as to be accessible and placed so as to minimize contamination. Food receptacles are kept clean and sanitary at all times.

Water is accessible at all times, except as dictated by veterinary treatment, for the health and comfort of the ferret. All water receptacles are kept clean and sanitary at all times.

Confinement and Control

Outside the home, Michigan law requires that ferrets be kept under control at all times. An owner shall prevent a ferret from leaving the owner’s property unless the ferret is confined or leashed and under the direct control of the owner or a responsible person designated by the owner.

A person shall not release a ferret into the wild or abandon a ferret. This prohibition is serious — releasing a ferret outdoors is not only a violation of state law but places the animal in danger, as domestic ferrets cannot survive in the wild.

Common Mistake: Some owners assume that because ferrets are small, they do not need to be leashed or confined when taken outside. Michigan law requires the same level of control for ferrets as for dogs when they leave your property. An unsupervised ferret off your property is a legal violation, not just a safety risk.

Veterinary Care for Hobby Breeders

The hobby breeder must establish a program of veterinary care with a veterinarian that includes regularly scheduled visits to monitor ferret health and husbandry. The hobby breeder’s veterinarian shall annually review the program of veterinary care required.

Additionally, a ferret with any congenital or developmental defect is not used in a breeding program or offered for stud or hire. This rule protects the health of future litters and limits the spread of hereditary conditions.

Michigan’s care standards for ferrets share some similarities with how the state approaches other small animal ownership. For comparison, you can review the backyard chicken laws in Michigan and beekeeping laws in Michigan to see how the state structures care requirements across different species.

Penalties for Illegal Ferret Ownership in Michigan

Michigan’s ferret statute includes a dedicated penalty section — MCL 287.899 — that creates a tiered system of misdemeanor offenses depending on what rule was violated.

Penalty Tiers Under Act 358

Violation Type | Classification | Consequence
Intentional violation of a quarantine condition | Misdemeanor | Costs of quarantine and prosecution, plus additional penalties
General violation of the act or its rules | Misdemeanor | Costs of prosecution, plus additional penalties
Allowing a ferret to leave the property without confinement or leash (Section 4(2)) | Misdemeanor | Fine of not more than $100.00 plus prosecution costs
Violation of breeding rules (Section 287.893) | Misdemeanor | Criminal misdemeanor charge

A person who intentionally violates a condition of a quarantine is guilty of a misdemeanor, and shall pay the costs of the quarantine and prosecution. In addition, the misdemeanor is punishable by one or more additional penalties. A person who violates this act or a rule promulgated under this act is guilty of a misdemeanor and shall pay the costs of the prosecution. A person who violates the confinement section is guilty of a misdemeanor punishable by a fine of not more than $100.00, and shall pay the costs of the prosecution.

Bite Reporting and Quarantine

If your ferret bites or scratches a person, Michigan law requires prompt action. A person who owns or harbors a ferret that has bitten, scratched, caused abrasions or contaminated with saliva or other infectious material an open wound or mucous membrane of a human being shall report the incident within 48 hours to the county public health department.

Following a potential rabies exposure, a quarantine period is standard. The national standard, recommended by the CDC, is a 10-day observation period for healthy dogs, cats, and ferrets suspected of rabies exposure. If your ferret was not vaccinated at the time of the bite, the consequences are more serious. For unvaccinated ferrets exposed to rabies, the quarantine extends to six months. The owner bears the costs of this extended confinement, which can run hundreds or even thousands of dollars depending on the facility.

Enforcement authority under Act 358 extends to law enforcement agents, animal control officers, and the director of the Michigan Department of Agriculture. In addition to any other action authorized by the act, a law enforcement agent, an animal control officer, or the director may bring an action to obtain a declaratory judgment that a method, act, or practice is a violation of this act, or obtain an injunction against a person who is engaging, or about to engage, in a violating practice.

Important Note: Keeping your ferret’s rabies vaccination current is the single most effective way to avoid the most serious legal and financial consequences under Michigan law. An up-to-date vaccine dramatically reduces the risk of a six-month quarantine and the costs and penalties that come with it.

Michigan takes animal-related violations seriously across the board. If you want to understand how broader animal cruelty enforcement works in the state, the animal cruelty laws in Michigan page covers the penalty structure in detail. Pet owners dealing with custody disputes or ownership questions may also find the pet custody laws in Michigan resource useful.

Staying Compliant as a Michigan Ferret Owner

Michigan’s ferret laws are detailed but manageable once you understand them. The core obligations for most pet owners come down to a short checklist: keep your ferret’s rabies vaccination current, never let your ferret roam unsupervised off your property, report any biting incident to the county health department within 48 hours, and check your local municipality for any licensing or ordinance requirements that apply in your area.

If you plan to breed ferrets, the rules become more involved. Hobby breeders who stay within the four-ferret threshold and meet all the care criteria can operate without a formal permit, but they must maintain a documented veterinary care program and follow strict housing, food, and health standards.

For any situation that feels unclear — especially if a local ordinance, a bite incident, or a quarantine is involved — consulting with a licensed Michigan attorney who handles animal law is the most reliable way to protect yourself and your pet. Laws can change, local ordinances vary widely, and the consequences of non-compliance under Act 358 are real. Staying informed is the first step toward responsible ownership.

Michigan residents who own or are considering other regulated animals may also want to review the wildlife removal laws in Michigan and the outdoor cat laws in Michigan for additional context on how the state regulates animal ownership and control more broadly.
