Lions are among the most powerful and recognizable animals on earth, and for some people, the idea of keeping one as a pet holds a certain appeal. But before you take that thought any further, you need to understand exactly what the law says — at the federal level, at the state level, and right in your own county or city.
If you live in Missouri and you’re wondering whether lion ownership is legal, the answer involves multiple layers of regulation that work together. This article walks you through each layer clearly so you know where you stand.
Is It Legal to Own a Lion in Missouri?
The short answer is: effectively no, not as a private pet. Missouri does not outright ban the possession of lions with a single sweeping prohibition, but the combination of state statute, federal law, and local ordinances makes private lion ownership essentially impossible for the average resident.
Under Missouri State Statute 578.023 RSMo, a person commits the offense of keeping a dangerous wild animal if they keep any lion, tiger, leopard, ocelot, jaguar, cheetah, margay, mountain lion, Canada lynx, bobcat, jaguarundi, hyena, wolf, bear, nonhuman primate, coyote, any deadly, dangerous, or poisonous reptile, or any deadly or dangerous reptile over eight feet long, in any place other than a properly maintained zoological park, circus, scientific or educational institution, research laboratory, veterinary hospital, or animal refuge — unless the animal is registered with the local law enforcement agency in the county where it is kept.
In plain terms, you cannot keep a lion in a private residence, on private land, or anywhere outside of a narrow list of approved institutional settings. Even the registration pathway that exists in the statute does not open the door to casual private ownership — it was designed for institutional or specialized keepers, not backyard arrangements.
Important Note: State law is only one piece of the puzzle. Federal law now places additional hard restrictions on lion ownership that apply to everyone in Missouri regardless of what the state statute says.
What Federal Law Says About Lion Ownership
Even if Missouri’s state law left any ambiguity, federal law closes the door firmly. The Big Cat Public Safety Act (BCPSA) is the controlling federal framework you need to understand.
The Big Cat Public Safety Act was enacted on December 20, 2022, to end the private ownership of big cats as pets and to prohibit exhibitors from allowing public contact with big cats, including cubs. The BCPSA placed new restrictions on commerce in and possession, breeding, and use of certain big cat species — referred to in the Act as “prohibited wildlife species” — to address threats to public safety posed by lions, tigers, leopards, snow leopards, clouded leopards, jaguars, cheetahs, cougars, and any hybrids thereof.
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, and this prohibition is narrowly focused on pet big cats while exempting zoos, sanctuaries, and universities.
You might wonder about people who already owned lions before the law passed. The Act includes an exception for private individuals or entities who owned big cats before the law was enacted on December 20, 2022. If you were a private big cat owner, you could keep your prohibited big cats under this law, provided you had registered each big cat in your possession with the U.S. Fish and Wildlife Service no later than June 18, 2023. That registration window is now closed. This means no new private lion ownership is possible under federal law, period.
Anyone who violates the Big Cat Public Safety Act faces up to $20,000 in fines and up to five years in prison. These are federal-level consequences, separate from anything Missouri might impose on top of them.
Key Insight: The Lacey Act also plays a role. The Big Cat Public Safety Act revised requirements governing the trade of big cats under the Lacey Act, which prohibits any person from importing, exporting, buying, selling, transporting, receiving, or acquiring big cats across state lines or the U.S. border — with exemptions provided for certain entities such as universities and wildlife sanctuaries.

Missouri’s Laws on Owning a Lion
At the state level, Missouri’s primary tool for regulating dangerous wild animals is RSMo 578.023. It is worth reading closely because the language matters.
Under the statute, a person commits the offense of keeping a dangerous wild animal if they keep any lion, tiger, leopard, ocelot, jaguar, cheetah, margay, mountain lion, Canada lynx, bobcat, jaguarundi, hyena, wolf, bear, nonhuman primate, coyote, any deadly, dangerous, or poisonous reptile, or any deadly or dangerous reptile over eight feet long, in any place other than a properly maintained zoological park, circus, scientific or educational institution, research laboratory, veterinary hospital, or animal refuge, unless they have registered such animals with the local law enforcement agency in the county in which the animal is kept.
Notice what the statute does and does not say. It does not say “you may never own a lion.” Instead, it says you cannot keep one outside of specific approved facilities unless you register with local law enforcement. However, the registration pathway was not designed to allow private citizens to keep lions as household pets — it was designed to create a record of animals already held in sanctioned settings.
It is against the law to keep lions, tigers, leopards, ocelots, jaguars, cheetahs, margays, mountain lions, Canada lynxes, bobcats, jaguarundis, hyenas, wolves, bears, nonhuman primates, or coyotes in Missouri outside of those narrow institutional exceptions. Combined with the federal ban on new private ownership, a private individual in Missouri has no legal path to acquiring a lion today.
Missouri’s Department of Conservation also maintains a permit system for various wildlife categories. African lions are not governed by the Missouri Department of Conservation, which means the state’s wildlife permit framework — designed largely for native or game species — does not provide an alternative route to lion ownership either.

Permits and Requirements for Lion Ownership in Missouri
Given the federal prohibition on new private lion ownership, there is no permit available to a private Missouri resident that would allow them to acquire a lion today. However, it is still useful to understand what the permit and registration landscape looks like for institutional or pre-existing situations.
In Missouri, you must get a permit from the Missouri Department of Agriculture’s Division of Animal Health, which is a non-negotiable requirement. Additionally, if you are bringing an animal into the state, you will need a health certificate from a veterinarian, and that certificate must be issued within seven days of the animal’s arrival, confirming the animal is free from specific diseases.
For the local registration component required by RSMo 578.023, the process works as follows:
- Many counties require you to register your exotic animal with the local sheriff’s office. For instance, the Cole County Sheriff’s Office mandates registration for specific dangerous animals, including lions, tigers, wolves, bears, and certain reptiles over eight feet long.
- The registration is intended to ensure that local law enforcement and first responders are aware of the presence of dangerous animals in their jurisdiction.
- 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.
Pro Tip: Even if you believe you qualify for an institutional exemption — such as operating an animal refuge or sanctuary — you still need to meet the requirements of both the federal Big Cat Public Safety Act and Missouri state law simultaneously. Consult a wildlife attorney before proceeding.
For qualified institutions such as accredited zoos, research facilities, and licensed sanctuaries, the pathway to legally housing a lion involves USDA licensing under the Animal Welfare Act, compliance with BCPSA exemption criteria, Missouri Department of Agriculture permitting, and local law enforcement registration. The BCPSA prohibits anyone except qualified entities like AZA-accredited facilities from possessing big cats.
It is also worth noting that just because an animal may appear permissible under one layer of law, many local cities and counties have their own restrictions on which animals are legal to keep. A permit or registration at one level does not override restrictions at another.
Local Laws That May Apply in Missouri
Missouri’s state statute sets a baseline, but individual cities and counties are free to pass stricter ordinances. This means that even if you somehow navigated the state-level registration process, your city or county may independently prohibit lion ownership with no exceptions.
You should check with your local city and county for their regulations regarding what animals you can and cannot own, and it is your responsibility to comply with all local laws, ordinances, and covenants before importing or possessing live wildlife.
Here are the types of local restrictions you may encounter across Missouri:
- City ordinances: Many Missouri cities, including larger urban centers like St. Louis and Kansas City, have municipal codes that prohibit keeping dangerous wild animals within city limits. Many exotic pets are prohibited within St. Louis City limits.
- County ordinances: Individual counties may require additional registration beyond the state’s requirement, or may ban certain animals outright even where state law is silent.
- HOA restrictions: Rules can vary by species, county, and even your neighborhood homeowners association. An HOA agreement can prohibit exotic animals on your property regardless of what any governmental body permits.
- Zoning laws: Agricultural or residential zoning classifications often dictate what types of animals may be kept on a given parcel of land, and lions would typically fall outside permitted uses in residential zones.
Common Mistake: Many people assume that if an animal is available for sale, it must be legal to own. That is a dangerous and often costly assumption. Availability at an exotic animal sale or online does not equal legal permission to keep the animal where you live.
If you’re interested in Missouri’s native wildlife instead, the state has a rich variety of animals worth exploring — from the many snake species found in Missouri to Missouri’s eagle populations and even the diverse spiders found across the state.
Penalties for Illegally Owning a Lion in Missouri
Violating Missouri’s dangerous wild animal law and the federal Big Cat Public Safety Act can result in serious consequences at multiple levels. Understanding the penalties is important whether you are considering ownership or simply want to understand the legal stakes.
Missouri State Penalties
The offense of keeping a dangerous wild animal under RSMo 578.023 is a class C misdemeanor. In Missouri, a class C misdemeanor can carry a jail sentence of up to 15 days and a fine of up to $750 per violation. While this may seem modest compared to federal penalties, the state charge is separate from — and in addition to — any federal prosecution.
Beyond the criminal classification, other state-level consequences can include:
- One of the most devastating penalties is having your animal confiscated by law enforcement. If you own a dangerous animal — like a lion, tiger, wolf, bear, or even certain reptiles over eight feet long — and you have not registered it, authorities have the right to take it from you.
- The financial penalties for violating exotic animal laws can be substantial. You could face fines of up to $10,000 for each infraction, and if you have multiple unregistered animals or are violating several different regulations, the costs can multiply quickly.
Federal Penalties Under the Big Cat Public Safety Act
Anyone who violates the Big Cat Public Safety Act faces up to $20,000 in fines and up to five years in prison. These penalties apply to possession, breeding, commerce, and public contact violations under the Act.
Federal enforcement is handled by the U.S. Fish and Wildlife Service’s Office of Law Enforcement, which has the authority to investigate, seize animals, and refer cases for federal prosecution.
Additional Consequences to Consider
| Violation Type | Governing Law | Potential Consequence |
|---|---|---|
| Keeping unregistered lion | RSMo 578.023 (State) | Class C misdemeanor; animal confiscation |
| Private lion possession (new acquisition) | Big Cat Public Safety Act (Federal) | Up to $20,000 fine; up to 5 years in prison |
| Interstate transport or sale of lion | Lacey Act / BCPSA (Federal) | Federal criminal charges; fines and imprisonment |
| Violation of local ordinance | City/County code | Additional fines; forced removal of animal |
| Breeding a lion privately | Big Cat Public Safety Act (Federal) | Up to $20,000 fine; up to 5 years in prison |
The state has strict rules for these specific species because of the potential danger they pose to the community. Losing a pet is heartbreaking under any circumstances, but having it confiscated due to a legal violation is an entirely preventable outcome — which underscores the importance of following every step of the registration process to the letter.
If you are passionate about lions and big cats, the most responsible and legal way to connect with them is through accredited zoos, wildlife sanctuaries, and conservation organizations. Missouri has several reputable facilities where these animals receive professional care. You might also channel that interest into learning about related wildlife — for example, what animals prey on mountain lions or exploring Missouri’s water bird species and other native wildlife that you can observe and appreciate without legal risk.
The legal framework surrounding lion ownership in Missouri is clear: state law restricts keeping lions to approved institutional settings with mandatory registration, and federal law has since closed the door entirely on new private ownership. Before considering any exotic animal, always consult with a licensed wildlife attorney and contact both the Missouri Department of Agriculture and your local law enforcement agency to understand every applicable requirement in your specific location.
