Illegal Pets in California: Restricted Species, Permits, and Penalties

Illegal pets in California cover a longer list than in any other state, and the surprises are the ones that catch people out: ferrets, hedgehogs, sugar gliders, and every species of monkey are all flatly banned, alongside the big cats, wolves, venomous snakes, and invasive fish you’d expect. The rules come from California Code of Regulations, Title 14, Section 671, which makes it illegal to import, transport, or possess any listed animal without a permit from the California Department of Fish and Wildlife.¹ Those permits are not issued for personal pet ownership, no matter how experienced the owner or how secure the enclosure.

The Mammals Most People Don’t Realize Are Banned

Three animals catch Californians off guard more than any others. Ferrets, hedgehogs, and sugar gliders are all popular pets in other states and all illegal here. Ferrets have been the subject of legalization campaigns for decades. In mid-2025, the California Fish and Game Commission approved a petition to consider removing ferrets from the restricted list, but the matter is still under review at CDFW and no final decision has been made. Until it is, a ferret is contraband.

The broader mammal bans are sweeping. All non-human primates are prohibited, meaning every species of monkey, ape, and lemur, with no exception for hand-raised or captive-bred animals. All bats are banned. So are all raccoons and their relatives.¹

Exotic carnivores are heavily restricted:

Big cats: tigers, lions, leopards, jaguars, cheetahs, snow leopards, and clouded leopards
Medium wild cats: servals, bobcats, lynx, and ocelots
Canids: wolves, coyotes, jackals, and all fox species, including fennec foxes
Bears of every species
Hyenas of every species

Rodents split into legal and illegal along species lines. Domesticated golden hamsters and guinea pigs are fine. Gerbils, degus, and most hamster species other than the golden are prohibited, as are wild-caught or non-domesticated strains of species that would otherwise be legal.¹

Wild pigs, most deer species, and various antelope are also restricted, largely because of the disease risk they pose to livestock and native deer.

Birds That Can’t Be Kept as Pets

Most native California birds are off-limits under the state Fish and Game Code, which makes possession of native wildlife illegal without authorization. That covers hawks, eagles, falcons, owls, crows, ravens, jays, magpies, and nearly every wild bird you’d encounter locally.² Federal law adds another layer: the Migratory Bird Treaty Act protects over a thousand migratory species from possession without a federal permit.³

Among exotic birds, the Monk Parakeet, also known as the Quaker Parrot, is specifically named on the restricted list because feral colonies build large communal nests on power lines and other infrastructure. Common pet birds like cockatiels, budgies, and standard parakeet varieties remain legal.¹

Reptiles and Amphibians That Are Off-Limits

Two groups drive the reptile restrictions. All venomous snakes are prohibited for private ownership, with limited exceptions for licensed professionals in research or education. Large constrictors, including most pythons and anacondas, are also restricted. All crocodilians, meaning alligators, crocodiles, caimans, and gharials, are illegal to own.¹

Native California reptiles and amphibians get separate protection. You cannot collect or keep any native wild reptile or amphibian without specific authorization. Picking up a California king snake from your yard and keeping it is illegal, even though a captive-bred king snake purchased from an out-of-state breeder is fine.

Plenty of common pet reptiles stay legal in California, including ball pythons, corn snakes, bearded dragons, leopard geckos, and most tortoise species that aren’t independently protected under endangered species laws.

Fish and Invertebrates on the Banned List

California’s waterways are especially vulnerable to invasive species, and the restricted list reflects that. Prohibited freshwater fish include piranhas, all snakehead species, walking catfish, and several species of Asian carp.¹ Many of these are federally listed as injurious wildlife under the Lacey Act, so moving them across state lines is a federal offense on top of the state ban.⁴

Zebra mussels and quagga mussels are banned outright, because a single introduction could clog water infrastructure and permanently alter freshwater ecosystems. Certain crayfish species are restricted for outcompeting native crayfish and transmitting crayfish plague.

Invertebrate restrictions focus on highly venomous scorpions and spiders and on species that threaten agriculture. Many common tarantula species stay legal; well-known pet-trade species like Chilean rose or Mexican red-knee tarantulas are fine.¹

Why an Animal Ends Up on the List

The California Fish and Game Commission has determined that none of the listed animals are “normally domesticated in this state,” which is the threshold separating restricted wildlife from standard pets. From there, the Commission looks at whether a species could survive California’s climate and establish a breeding population, whether it could compete with or prey on native wildlife, whether it carries diseases transmissible to humans or livestock, and whether it could damage crops or infrastructure.⁵ A hedgehog and a tiger land on the list for the same structural reason: both could thrive in California’s mild climate if released or escaped.

Federal Bans That Also Apply

Even if a species somehow slipped past California’s list, federal law often catches it. The Big Cat Public Safety Act, signed in December 2022, bans private ownership of eight big cat species nationwide: lions, tigers, leopards, snow leopards, clouded leopards, jaguars, cheetahs, and cougars. Hybrids like ligers and tigons are included. The law prohibits breeding, purchasing, or possessing any of these animals unless you’re a USDA-licensed exhibitor, an accredited sanctuary, a state university, or one of a few other narrow categories.⁶ Private owners who already had big cats when the law passed could keep them only by registering with the U.S. Fish and Wildlife Service by June 18, 2023. No new private acquisitions are allowed.⁷

The Lacey Act makes it a federal crime to move wildlife across state lines in violation of any state law. Bringing a hedgehog from Nevada or a fennec fox from Oregon into California triggers both a state and a federal violation. The Lacey Act’s injurious wildlife provisions separately ban importation and interstate transport of species the federal government has designated as invasive threats, including walking catfish, all snakeheads, various Asian carp, certain pythons and anacondas, brown tree snakes, and zebra mussels.⁴

Penalties If You’re Caught

Possessing a restricted animal without a permit is a misdemeanor under California Fish and Game Code. The baseline penalty is a fine of up to $1,000, up to six months in county jail, or both. That’s what most individual pet owners face.

The numbers climb sharply once money enters the picture. Illegally possessing, selling, or trading a restricted animal for profit or personal financial gain carries a minimum fine of $5,000 and a maximum of $40,000, with up to one year in jail. A second or subsequent for-profit offense carries a minimum $10,000 fine and a maximum of $50,000.⁸ Prosecutors have up to three years after the offense to bring charges.

CDFW will also seize the animal. You’re responsible for the costs of investigation, temporary care, and eventual placement or euthanasia, which can run high for large or specialized species.

Federal penalties stack on top when state lines are involved. A Lacey Act injurious wildlife violation carries up to six months in prison and a federal fine.⁹ Knowingly selling or buying illegal wildlife worth more than $350 across state lines can mean up to five years in federal prison and fines up to $20,000.¹⁰

Can You Get a Permit?

CDFW does issue restricted species permits, but not for pets. Permits go to accredited zoos and aquariums, registered aquaculturists, and approved scientific research or educational programs.¹¹ There is no exotic pet enthusiast category. Experience, enclosure design, and previous ownership in another state make no difference. If the animal is on the list, private ownership is not permittable.

What to Do If You Already Own One

Plenty of people are in this position: you bought a hedgehog while living in Arizona and moved here, or a friend gave you a sugar glider before you knew the rules. Doing nothing is the worst option. Veterinarians can report illegal animals, neighbors can file complaints, and a traffic stop during a move can turn into a wildlife case.

The practical paths are surrendering the animal to a licensed rescue or sanctuary that can legally house it, rehoming it to someone in a state where it’s legal, or contacting CDFW directly. California does not have a formal statewide amnesty program that guarantees no penalties for voluntary surrender, so exposure depends on the specific facts and how cooperatively you approach the department. Enforcement officials tend to work more constructively with owners who come forward than with those discovered during inspections. Talking to a wildlife attorney before contacting CDFW can help you understand your exposure and negotiate the best resolution available.
