Few questions in exotic animal law are as layered as whether you can own a lion in Idaho. The short answer is no — not as a private pet — but the full legal picture involves state classifications, a federal law passed in 2022, and local ordinances that can add yet another layer of restriction on top of everything else.
If you have been researching lion ownership in Idaho, or you simply want to understand how the Gem State handles big cats, this guide walks through every level of the law that applies to you. Understanding each layer is important before you spend money on an animal, a facility, or a permit application.
Is It Legal to Own a Lion in Idaho?
The direct answer is that private lion ownership is not legal for ordinary residents in Idaho. Some deleterious exotic animals are not just permit-required — they can only be kept at facilities accredited by the Association of Zoos and Aquariums (AZA). For practical purposes, this makes private ownership impossible. Large cats, including caracals, cheetahs, jaguars, leopards, lions, and tigers, can only be possessed on AZA-accredited grounds.
This means that even if you could satisfy every other requirement Idaho law imposes, you still could not keep a lion at a private residence or on private property. The AZA-only restriction effectively closes the door on private lion ownership in the state. On top of that, a federal law enacted in 2022 adds a nationwide prohibition that applies regardless of what any individual state permits.
Key Insight: Idaho classifies lions under two overlapping frameworks — the state’s deleterious exotic animal rules and the federal Big Cat Public Safety Act. Both must be satisfied simultaneously, and neither allows a private individual to keep a lion at home.
What Federal Law Says About Lion Ownership
The Big Cat Public Safety Act was enacted December 20, 2022, to end the private ownership of big cats as pets and prohibit exhibitors from allowing public contact with big cats, including cubs. This is a federal law, which means it applies in every state — including Idaho — regardless of what state rules say.
The Big Cat Public Safety Act refers to big cats as “prohibited wildlife species.” The prohibited wildlife species listed in the Act include lions (Panthera leo), tigers, leopards, snow leopards, clouded leopards, cheetahs, jaguars, and cougars, along with any hybrids of these species. Owning, breeding, or acquiring any of these animals as a private individual is now a federal violation.
The law amends the Captive Wildlife Safety Act to prohibit the private possession of lions, tigers, leopards, cheetahs, jaguars, cougars, or any hybrid of these species. This prohibition is narrowly focused on pet big cats and exempts zoos, sanctuaries, and universities. So if you are affiliated with a qualifying institution, different rules may apply — but that exemption does not extend to private individuals.
There was a narrow grandfather provision for people who already owned big cats before December 20, 2022. Even if your state law allows private big cat ownership, you must have registered your big cat with the USFWS by June 18, 2023, unless another exception of the Act applies. Public contact with big cat cubs had to cease immediately, and private owners had 180 days to register their cats with the U.S. Fish and Wildlife Service. Only 27 did. Those who registered may keep the cats they have but cannot acquire more. That registration window is now permanently closed.
The federal law also interacts with the U.S. Fish and Wildlife Service‘s enforcement authority. It is your responsibility to follow all local, state, tribal, and federal laws and regulations regarding prohibited wildlife species. Registration under the Big Cat Public Safety Act does not constitute authorization to engage in any activity prohibited by such laws and regulations.

Idaho’s Laws on Owning a Lion
At the state level, Idaho regulates lions through its deleterious exotic animal framework. Idaho regulates exotic animal ownership through two separate state agencies, each with its own rulebook. The Idaho State Department of Agriculture (ISDA) controls “deleterious exotic animals” under IDAPA 02.04.27, while the Idaho Department of Fish and Game (IDFG) governs wildlife possession under IDAPA 13.01.10.
The Idaho State Department categorizes these banned pets as deleterious exotic animals as “animals which have been determined by ISDA to be dangerous to people, the environment, livestock, agriculture, or wildlife of the state.” Lions meet every element of that definition. Species of deleterious exotic animals include leopards, lions, non-pinioned mute swans, Russian wild boar, and all non-human primates, among others.
Idaho’s approach to large felids is stricter than its approach to many other regulated species. While some deleterious exotic animals can be possessed with a permit anywhere in the state, all large felidae may only be possessed on AZA-accredited facilities. This category includes caracals, cheetahs, jaguars, leopards, lions, and tigers. No amount of permitting work will change this restriction for a private property owner.
The state also prohibits releasing any deleterious exotic animal within Idaho. No person may transfer, sell, barter, trade, change ownership, or change possession of any deleterious exotic animal, unless the person receiving the deleterious exotic animal has obtained a possession permit, issued by the Administrator, prior to the animal being transferred. This applies to lions as much as to any other regulated species, meaning even gifting or rehoming a lion without the recipient holding a valid permit is a violation.

Permits and Requirements for Lion Ownership in Idaho
Because lions are restricted to AZA-accredited facilities, the permit process described below applies to the institutions that could theoretically hold lions — not to private individuals. That said, understanding what Idaho’s permit system requires helps explain why private lion ownership is effectively impossible even before the AZA restriction is considered.
Obtaining a Deleterious Exotic Animal Possession Permit involves multiple steps. Applicants must complete the official application through ISDA, providing personal information including Social Security Number or Employer Identification Number, detailed facility descriptions with maps and legal property descriptions, and escape prevention protocols. The facility must be available for inspection at least seven days before animals arrive.
The review process goes well beyond paperwork. The Administrator will review the possession permit application and, in determining whether to issue the possession permit, consider factors relating to protection of the state’s agriculture industry, the wildlife of the state, and the environment. Such factors include, but are not limited to, the proximity of the facility to farms, ranches, wildlife migration routes, and other areas in which native Idaho wildlife may commonly be found.
Applications must also include a named Idaho-licensed veterinarian who will provide care for the animals, a written statement of the applicant’s training and experience with the species, and a written escape response plan. Permit holders must maintain proper containment meeting zoo standards, microchip and tattoo all animals for identification, submit annual inventories reporting births, deaths, and transfers, and report any animal escapes within 24 hours.
| Permit Requirement | Details |
|---|---|
| Facility type | AZA-accredited only for lions and other large felids |
| Application | Submitted to ISDA Division of Animal Industries |
| Facility inspection | Must be available at least 7 days before animals arrive |
| Veterinary care | Named Idaho-licensed veterinarian required |
| Animal identification | Microchip required for all mammals |
| Annual inventory | Must report births, deaths, and transfers |
| Escape reporting | Must notify the Administrator within 24 hours |
| Federal compliance | Big Cat Public Safety Act prohibits new private acquisitions |
Importing a lion from another state adds another layer. No person may import any deleterious exotic animal into the state unless the deleterious exotic animal is accompanied in transit by an import permit issued by the Administrator and an official certificate of veterinary inspection. Possession and importation are treated as two separate processes, each with its own requirements.

Local Laws That May Apply in Idaho
State law sets the floor for lion regulation in Idaho, but cities and counties can go further. City and county ordinances can impose restrictions beyond what state law allows, so checking local rules before acquiring any exotic animal is just as important as understanding the state framework.
Even with state permits, local restrictions can prohibit exotic pet ownership. Cities and counties maintain independent authority to ban animals that state law permits. Before investing in permits or animals, contact your local animal control office to verify no additional prohibitions exist.
This matters even for entities like zoos or sanctuaries that might otherwise qualify to hold lions under the AZA framework. A municipality could have a zoning ordinance, an animal control code, or a land-use restriction that prevents a qualifying facility from operating within its boundaries. Boise, Idaho Falls, Nampa, and other cities each maintain their own animal control codes that could affect where and how any large predator may be kept.
Important Note: Local rules vary widely and change independently of state law. Always contact your county assessor’s office, city planning department, and local animal control agency before making any decisions about exotic animal facilities in your area.
While your state may allow you to keep certain animals as pets, local laws can restrict ownership. State laws are frequently changing in response to concerns for public safety and animal well-being. You should always double-check for any new or proposed state or local legislation.

Penalties for Illegally Owning a Lion in Idaho
Owning a lion without proper authorization in Idaho exposes you to penalties at both the state and federal levels. The two frameworks operate independently, meaning a violation can trigger consequences from multiple agencies at the same time.
State-level penalties under IDAPA 02.04.27 are significant. The Idaho State Department of Agriculture defines deleterious exotic animals as non-native species dangerous to people, livestock, agriculture, or wildlife. Possessing these animals without proper authorization violates IDAPA 02.04.27, Idaho’s Rules Governing Deleterious Exotic Animals, and can result in significant penalties including fines up to $1,000, jail time up to six months, and mandatory animal surrender.
Beyond fines and potential jail time, the state can also revoke any existing permits. Permits issued pursuant to this chapter may be revoked at any time if the Administrator finds violations of any of the provisions of this chapter. A revocation would affect all deleterious exotic animals in your possession, not just the lion in question.
Federal penalties under the Big Cat Public Safety Act are separate and can be substantially harsher. The Lacey Act makes it illegal to import, export, transport, sell, or acquire any wildlife taken or possessed in violation of state, federal, tribal, or foreign law. Penalties under the Lacey Act include both civil and criminal sanctions and can be significantly harsher than state-level fines.
There are also practical consequences beyond the legal penalties. Standard homeowner’s and renter’s insurance policies routinely exclude exotic animals from liability coverage. Commercial general liability policies often contain explicit animal liability exclusions that cover reptiles, monkeys, snakes, and “any exotic animals, including but not limited to lions, tigers or alligators.” If your exotic pet injures someone or damages property and your insurance doesn’t cover it, you’re personally liable for the full amount.
- State fines up to $1,000 per violation under IDAPA 02.04.27
- Up to six months in jail for state-level violations
- Mandatory surrender of the animal to state authorities
- Permit revocation affecting all regulated animals in your care
- Federal civil and criminal penalties under the Lacey Act and Big Cat Public Safety Act
- Full personal liability for any injuries or property damage the animal causes
The U.S. Fish and Wildlife Service handles enforcement of the federal Big Cat Public Safety Act, while the Idaho State Department of Agriculture enforces state rules. Both agencies can act simultaneously if a violation involves both state and federal law. If you have questions about a specific situation, consulting an attorney familiar with Idaho’s animal law statutes is the most reliable path forward.
