Can You Own a Cougar in Massachusetts? What State and Federal Law Allow
September 18, 2026
Can you own a cougar in Massachusetts? Short answer: no, not as a private pet, and federal law closed most of the remaining loopholes back in 2022. Between a national ban on private big cat possession and one of the strictest state wildlife codes in the country, anyone hoping to keep a cougar as a household companion in the Bay State runs into legal walls at nearly every level.
This guide walks through exactly why that’s the case, what the federal Big Cat Public Safety Act changed, how Massachusetts regulators treat cougars under state law, and what happens to people who try to keep one anyway.
Is It Legal to Own a Cougar in Massachusetts
No. In Massachusetts, the private possession of certain wild and exotic animals is prohibited unless a person obtains a license from the Massachusetts Division of Fisheries and Wildlife (MassWildlife), which is only granted for certain scientific, educational, or exhibition purposes rather than personal pet-keeping. Cougars fall squarely into the category of animals that private residents cannot legally acquire, house, or breed in the state.
The state has banned certain exotic animals from being owned as pets, including primates, wolves, bears, and large cats, with big cats specifically covering lions, tigers, leopards, cougars, cheetahs, and African servals. This puts Massachusetts in the same restrictive category as most of New England, in contrast to states like Nevada or Alabama, where big cat ownership has historically required no license at all.
If you’ve already looked into other unusual pets in the state, this pattern will feel familiar. Massachusetts takes the same approach with alligator ownership and capybara ownership: rather than listing every banned species, regulators publish a short list of what you can keep and treat everything else as off-limits by default.
Pro Tip: Before assuming any exotic animal is legal in Massachusetts, check the state’s exemption list first. If a species isn’t named on it, the safest assumption is that you cannot legally possess it without a permit that private individuals rarely qualify for.
What Federal Law Says About Cougar Ownership
Even in states with looser rules, federal law now overrides most private cougar ownership arrangements. The Big Cat Public Safety Act, signed into law on December 20, 2022, amends the Captive Wildlife Safety Act to prohibit the private possession of lions, tigers, leopards, cheetahs, jaguars, cougars, or any hybrid of these species.
The law makes it unlawful to import, export, transport, sell, receive, acquire, or purchase in interstate or foreign commerce, or to breed or possess prohibited wildlife species including cougars, with certain exceptions. Those exceptions are narrow and mostly apply to institutions, not individuals:
- USDA Class C exhibitor license holders
- State universities and accredited wildlife sanctuaries that prohibit direct public contact
- Veterinarians and trained professionals under specific, non-commercial conditions
- Conservation programs meeting additional federal restrictions
Owners who already had big cats before the act’s enactment were allowed to keep them, but only if they registered the animals with the U.S. Fish and Wildlife Service. That registration window closed 180 days after enactment, on June 18, 2023, and registration is no longer open. In practice, this means anyone acquiring a cougar today has no legal registration path under federal law, regardless of what any individual state might otherwise allow.
| Legal Layer | What It Covers | Bottom Line for Private Owners |
|---|---|---|
| Federal (Big Cat Public Safety Act) | Interstate commerce, breeding, possession, exhibition contact | New private ownership effectively banned nationwide since 2022 |
| Massachusetts state law (M.G.L. c. 131, § 23) | In-state possession, permitting, exemption list | Cougars excluded from the exemption list; permits reserved for licensed institutions |
| Local ordinances | Zoning, nuisance animal rules, animal control bylaws | Can add restrictions but cannot override state or federal bans |
Massachusetts’s Laws on Owning a Cougar
In Massachusetts, the possession of wild or exotic animals is regulated by both state statutes and regulations enforced by the Massachusetts Division of Fisheries and Wildlife, which prohibits the possession of certain wild animals without a permit. The statutory foundation sits in Massachusetts General Laws Chapter 131, Section 23, with implementing regulations at 321 CMR 9.01.
Rather than naming every prohibited species, the regulation establishes a list of wild, non-domesticated vertebrate animals which may be imported, sold, or possessed without a permit, and treats anything left off that list as requiring a license MassWildlife rarely, if ever, grants to private individuals for a species like a cougar. This is the same exemption-list structure that governs whether residents can legally keep certain snake species or the smooth green snake without a permit, since reptiles that make the exemption list are treated very differently from mammals that never appear on it.
Regulators have been direct about how strict this framework is. MassWildlife has described the state’s approach to wildlife possession as being among the most restrictive in the country, and the agency’s default posture toward large predators like the cougar (Puma concolor) reflects that stance. The state has banned certain exotic animals from being owned as pets, such as primates, wolves, bears, and large cats, placing cougars in the same non-negotiable category as tigers and lions rather than treating them as a borderline case.
It’s worth noting that Massachusetts also protects native wildlife more broadly. If you’re curious how the state treats animals already living in its ecosystems, resources on endangered species in Massachusetts and what happens when black bears emerge from hibernation each spring show the same MassWildlife jurisdiction at work, just applied to wild populations instead of captive ones.
Permits and Requirements for Cougar Ownership in Massachusetts
MassWildlife does issue permits for wild animal possession, but not for the purpose most people have in mind. Permits may be granted for exhibition, educational, or scientific purposes, and applicants must meet specific criteria to qualify. A private resident hoping to keep a cougar as a household pet does not fit any of those categories.
Permits for other exotic animals are only granted after a thorough inspection process by the Department of Fisheries and Wildlife, which ensures the animal is being kept in a suitable environment and that the owner has the knowledge and resources to properly care for it. For cougars specifically, this inspection standard is largely moot, since the species is treated as banned for private possession outright rather than merely permit-restricted.
Institutions that do qualify, such as accredited zoos or USDA-licensed sanctuaries, face additional restrictions layered on top of any state permit. Massachusetts law now protects elephants, big cats, primates, giraffes, and bears from being used in any performance, exhibition, fair, animal act, circus, ride, trade show, petting zoo, carnival, parade, or race for public entertainment. That prohibition on traveling acts using animals like lions, tigers, bears, elephants, giraffes, and primates for entertainment took effect January 1, 2025, which means even licensed facilities cannot use a permitted cougar for public shows or photo opportunities.
Important Note: A Massachusetts wildlife permit and federal compliance under the Big Cat Public Safety Act are two separate requirements. Meeting one does not satisfy the other, and an institution needs both a state license and a valid federal exemption (such as USDA Class C status) to legally possess a cougar.
Local Laws That May Apply in Massachusetts
State law sets the floor, not the ceiling. Local municipalities may have additional rules on top of whatever MassWildlife and federal law already require, and those local layers matter even in the unlikely event someone obtained state and federal approval for a cougar.
Cities and towns across Massachusetts regulate animals through zoning bylaws, public health board rules, and animal control ordinances. These are the same local mechanisms that produce rules like dog breed restrictions and leash requirements in individual municipalities, and they extend just as easily to exotic or dangerous animal keeping. A town’s animal control officer or board of health can typically act on a nuisance or public-safety basis even without a species-specific bylaw, similar to how officers handle complaints in situations like a neighbor’s animal wandering onto private property.
Because these local rules vary by city and county, you might wonder whether a permissive-sounding town could effectively allow what the state forbids. It can’t. Local governments can add restrictions on top of state and federal law, but they cannot grant permission to do something that MassWildlife and the Big Cat Public Safety Act already prohibit.
Penalties for Illegally Owning a Cougar in Massachusetts
Penalties apply at both the state and federal level, and they can stack. Massachusetts has strict penalties for those who violate exotic animal laws or mistreat exotic animals, and offenders can face fines along with the loss of the animal itself. Violations of Massachusetts wildlife possession law can result in fines and potential loss of ownership, meaning MassWildlife can seize an illegally possessed cougar regardless of how it was acquired.
Federal penalties under the Big Cat Public Safety Act are considerably steeper. A person who knowingly violates the act can be fined up to $20,000, imprisoned for up to five years, or both, with each violation treated as a separate offense. The act also extends forfeiture provisions to any big cats bred or possessed in violation of the law, so an owner risks losing the animal on top of facing fines or prison time.
These aren’t theoretical numbers. Federal prosecutors have already brought cases under the law: a federal grand jury indicted two defendants in March 2024, one for violating the Big Cat Public Safety Act and the other for concealing that violation, and both pled guilty in October 2024. Violation of the act is punishable by up to five years’ imprisonment and a fine of up to $10,000 in that specific case, illustrating how sentencing can vary even though the statutory maximum runs higher.
Pro Tip: If you already have questions about penalties for wildlife-related violations in Massachusetts, similar enforcement logic applies to other regulated activities, from roadkill possession rules to hunting season requirements. MassWildlife treats unauthorized possession of any regulated species seriously, not just exotic mammals.
Combined, the federal and state penalty structures leave almost no upside for anyone considering an illegal cougar acquisition in Massachusetts. Between MassWildlife’s confiscation authority, the Big Cat Public Safety Act’s criminal exposure, and the near-total absence of a private ownership permit pathway, the legal risk far outweighs any appeal of keeping a big cat at home. Anyone genuinely interested in cougars is better served supporting accredited sanctuaries or wildlife conservation programs, which offer a legal and far safer way to engage with the species.
