Yes, ferrets are illegal to own as pets in California. The state classifies them as restricted wildlife under the Fish and Game Code and the California Code of Regulations, and has held that position since 1933. Getting caught with one can mean a misdemeanor charge, civil fines up to $10,000, and confiscation of the animal. California and Hawaii are the only two states with a statewide ban.
What the Law Actually Says
Two provisions do the work. California Code of Regulations Title 14, Section 671 lists restricted animals that cannot be imported, transported, or possessed without a permit from the California Department of Fish and Wildlife. Ferrets are named explicitly under Order Carnivora, Family Mustelidae, and carry a “(D)” designation, meaning the state considers them detrimental to native wildlife, agriculture, or public safety.1Cornell Law. California Code of Regulations Title 14, Section 671 – Importation, Transportation and Possession of Live Restricted Animals
Fish and Game Code Section 2118 reinforces the ban, making it illegal to import, transport, possess, or release any animal from the Mustelidae family, which the statute calls “undesirable and a menace to native wildlife, the agricultural interests of the state, or to the public health or safety.”2California Legislative Information. California Fish and Game Code FGC 2118 Between the two, it is illegal to bring a ferret into California, keep one you already have, or move one around within the state.
Penalties for Possession
Fish and Game Code Section 2125 lays out the penalties, and they come in two layers that can stack. The criminal side is a misdemeanor: up to six months in county jail, a fine of up to $1,000, or both. On top of that, a separate civil penalty of $500 to $10,000 can be imposed for each violation.3California Legislative Information. California Fish and Game Code FGC 2125
The civil penalty can be pursued by the state Attorney General, a local district attorney, or a city attorney, and the government can also recover the costs of seizing and holding the animal. A first-time owner discovered with a single pet ferret is more likely to receive a citation and lose the animal than to see jail time. Repeat violations, or cases involving breeding and sales, raise the exposure sharply.
Confiscation is the immediate practical consequence most owners face. When CDFW officers take a ferret, the animal may be transferred to a wildlife facility outside California. If no placement is available, the ferret may be euthanized. Some municipalities layer on their own local penalties, and landlords can pursue lease violations against tenants keeping illegal animals.
How Enforcement Actually Works
CDFW does not run ferret patrols, but investigations do happen. Most start with tips from neighbors, reports from veterinary clinics, or complaints filed with animal control. Veterinarians sit in an awkward spot: treating a ferret means handling an animal the client cannot legally possess, and some California clinics decline ferret patients entirely to avoid the entanglement.
When CDFW receives a credible report, officers may visit the property, issue a citation, and confiscate the animal. First offenses involving a single pet ferret often end in a citation and confiscation rather than prosecution, though the civil penalty still applies. Cases involving breeding, selling, or importing multiple ferrets get treated far more seriously and can lead to misdemeanor prosecution, asset forfeiture, and referral to federal authorities.
Day-to-day enforcement risk for any single owner is relatively low, but it spikes the moment a ferret needs veterinary care, a neighbor complains, or a landlord discovers the animal. Owners who keep ferrets illegally have no legal recourse if the animal is confiscated, and they cannot obtain rabies vaccinations through normal veterinary channels in the state.
Can a Ferret Be a Service or Emotional Support Animal?
No. Under the Americans with Disabilities Act, service animals are limited to dogs and, in some settings, miniature horses. Ferrets do not qualify.4eCFR. 28 CFR 35.136 – Service Animals
Emotional support animals are a broader category. HUD guidance requires housing providers to make reasonable accommodations for assistance animals, and that can include species other than dogs.5U.S. Department of Housing and Urban Development. Assistance Animals But HUD’s rules include an exception when the specific animal poses a direct threat to the health or safety of others that no accommodation can eliminate. California treats ferrets as a menace to public safety and native wildlife by statute, which gives housing providers and enforcement agencies strong grounds to deny a ferret ESA request. No federal court has forced California to allow ferret possession under the Fair Housing Act, and an ESA letter is not a reliable shield against state enforcement.
Are There Any Permits?
CDFW does issue permits to possess restricted species, but they are not available for private pet ownership. Permits under Section 671.1 are reserved for universities, government research agencies, laboratories, and wildlife educators doing work with a legitimate public benefit.6California Department of Fish and Wildlife. Restricted Species Permits If you want a ferret as a companion, there is no permit path.
What to Do If You Already Have a Ferret in California
Two options: surrender the animal or move it out of state.
Voluntary surrender is the cleanest way back to compliance. CDFW accepts surrendered animals through wildlife rehabilitation centers, animal control agencies, or directly through CDFW officials. Voluntary surrender generally does not result in fines or criminal charges, unlike confiscation during an enforcement action. You will need to sign a relinquishment form giving up ownership. The ferret may be placed with a wildlife facility or rescue outside California; if no placement exists, euthanasia is a real possibility.
Relocating a ferret to a legal state takes planning. Most states require an interstate health certificate signed by a licensed veterinarian within 30 days of travel, along with proof of current rabies vaccination.7USDA APHIS. United States Interstate and International Certificate of Health Examination for Small Animals The receiving state may have its own import rules on top of the federal requirements, so check those before you travel.
Air options are limited. No domestic airline currently allows ferrets in the cabin. Some carriers, such as Alaska Airlines, accept ferrets in climate-controlled cargo, and specialized pet shipping services can arrange transport. Driving to a neighboring state like Nevada or Oregon, where ferrets are legal, is the most straightforward route. Ferret rescue organizations sometimes help California residents rehome pets across state lines.
Bringing a Ferret Into California Adds Federal Exposure
Transporting a ferret into California from another state doesn’t just break California law. It can also trigger federal liability under the Lacey Act, which makes it illegal to transport wildlife across state lines in violation of state law.8Office of the Law Revision Counsel. 16 USC 3372 – Prohibited Acts
Federal penalties scale with the conduct. A knowing violation of the trafficking prohibitions carries up to five years in federal prison and fines up to $250,000 for an individual. A lower-level “should have known” violation still carries up to one year in prison and fines up to $100,000. The maximums are aimed at commercial trafficking, so someone moving a single pet ferret is unlikely to face them. Federal scrutiny becomes far more likely if authorities find evidence of breeding, selling, or smuggling multiple animals across the border.9U.S. Fish and Wildlife Service. Lacey Act
Is the Law Likely to Change?
Not soon. Advocacy groups have pushed to legalize ferrets in California for decades without success. Assembly Bill 647 in 2005 would have required an environmental assessment and, if the assessment found no significant threat to California wildlife, would have legalized ownership of spayed or neutered, rabies-vaccinated ferrets.10California Legislative Information. AB 647 Assembly Bill – Bill Analysis It did not pass. Senate Bill 89 in the 2003–2004 session proposed an amnesty for ferrets already in the state and also stalled. Subsequent bills have met the same fate.
CDFW has consistently opposed legalization, arguing that the ecological and public health risks outweigh the benefits. Advocates point out that 48 other states manage legal ferret ownership without ecological disaster. The ban remains firmly in place, and no pending legislation as of 2026 appears likely to change it.
