Can You Own an Iguana in Wyoming? What Wyoming Law Actually Requires

If you’ve been eyeing a green iguana for your Wyoming home, the short answer is yes, you can own one, but not without paperwork. Wyoming treats iguanas as exotic wildlife rather than an ordinary household pet, which means a state permit stands between you and legal ownership. Before you bring one home, it helps to understand exactly what the Wyoming Game and Fish Department expects, whether your city adds its own rules, and what happens if you skip the process altogether.

This guide walks through each piece of that puzzle, from invasive species concerns to the penalties for getting it wrong.

Is It Legal to Own an Iguana in Wyoming

Owning an iguana in Wyoming is legal, but it falls under the state’s exotic wildlife framework rather than a simple pet-ownership rule. Wyoming statute defines exotic species broadly, and the Wyoming Game and Fish Department’s own guidance is direct about what that means for anyone hoping to bring one home: prior to importing, possessing or transporting live wildlife in Wyoming, a permit is required.

That requirement exists because an iguana doesn’t fit the state’s narrow list of automatically exempt pets. Common pets such as domestic varieties of dogs, cats, gerbils, hamsters, mice, rats, guinea pigs and ferrets are exempted from Wyoming Game and Fish Commission regulations. Iguanas aren’t on that list, so they fall under the state’s cold-blooded wildlife permitting system instead.

It’s worth noting that Wyoming’s stricter exotic animal law, the Exotic Animal Ownership and Transfer Act, targets a different category of animal. This act, passed in 2013, prohibits the ownership, possession, sale, and distribution of certain exotic animals, including big cats, bears, non-human primates, and venomous reptiles. A standard pet iguana isn’t venomous and doesn’t fall into any of those banned categories, which is why permitted ownership remains possible. If you’re weighing an iguana against other unconventional pets, you might also compare notes with residents who’ve gone through similar permitting for a hedgehog or looked into whether it’s legal to keep a raccoon, since both require navigating the same general permitting structure.

Pro Tip: Apply for your permit before you purchase or bring an iguana into Wyoming. Retroactive applications for an animal you already possess can complicate the review process.

Is the Iguana Considered an Invasive Species in Wyoming

The green iguana (Iguana iguana) is not native to Wyoming, or to any part of the continental United States for that matter. Iguana iguana is native to parts of Central and South America along with a few eastern Caribbean islands. It reached the U.S. entirely through the exotic pet trade, arriving as escaped or intentionally released animals decades ago.

In warmer states, that history has created a genuine ecological problem. Feral populations exist in South Florida, including the Florida Keys, Hawaii, the U.S. Virgin Islands, and the Rio Grande Valley of Texas. Wikipedia’s overview of the species confirms the pattern spreading further: Hawaii, Texas, and Puerto Rico have labeled these animals as invasive as well. Florida’s response has been the most aggressive, where new rules make it illegal to sell, own, or breed green iguanas, Burmese pythons, tegus and a dozen other invasive reptiles.

Wyoming’s climate tells a different story. The state’s long, cold winters make it virtually impossible for an escaped or released iguana to establish a wild population here, unlike the subtropical conditions that let the species thrive in Florida. That’s why Wyoming doesn’t list the iguana as an invasive species threat the way Florida or Hawaii does.

State or Territory	Iguana Status
Florida	Established invasive population, prohibited species list
Hawaii	Labeled invasive
Texas (Rio Grande Valley)	Established feral population, labeled invasive
Puerto Rico	Widespread invasive population
U.S. Virgin Islands	Established feral population
Wyoming	No established wild population; climate limits survival outdoors

Even without an invasive species designation, Wyoming still regulates the iguana as exotic wildlife rather than treating it as a low-risk hobby pet, which brings us to the permitting process itself.

Permits and Registration Requirements in Wyoming

Every iguana kept in Wyoming needs to be covered by a permit issued through the Wyoming Game and Fish Department, and the paperwork traces back to how the state classifies exotic wildlife. Exotic species means any wild animals, including amphibians, reptiles, mollusks, crustaceans or birds not found in a wild, free or unconfined status in Wyoming. That definition covers your iguana squarely, since none of the roughly 40 iguana species are native to the state.

The relevant regulation is Chapter 69, which governs the importation and possession of live cold-blooded wildlife statewide. Reference sites tracking Wyoming’s rules point to this same chapter as the controlling authority: Chapter 69, Importation and Possession of Live Cold-Blooded Wildlife, Section 8, covers prohibited cold-blooded species. Before applying, it’s worth checking that section to confirm your particular iguana species isn’t on the restricted list, since a permit won’t be issued for any animal that falls into that category.

Once a permit is granted, it comes with ongoing obligations, not just a one-time approval. As Wyoming’s own regulatory code states, permit holders shall comply with all conditions of the permit issued, and any applicable Wyoming statutes, Commission regulations, federal statutes, county and municipal rules or ordinances. That last phrase matters: your state permit doesn’t override local rules, a point covered in more detail below.

Permit Type	Governing Regulation	What It Covers
Live Wildlife Possession Permit	WGFD Chapter 69	Non-native reptiles and amphibians, including standard pet iguanas
Commercial Use Permit	WGFD Chapter 10 reference within Chapter 69	Breeding, selling, or exhibiting reptiles commercially
Dangerous Species Permit	Exotic Animal Ownership and Transfer Act	Venomous reptiles, big cats, bears, and primates (not typically needed for iguanas)

Broader state-law summaries reinforce that the requirement isn’t unique to iguanas. Exotic species and nongame species requiring a permit for possession include, but are not limited to, parrots, ferrets, hedgehogs, pythons, boas, and other snakes. If you’re already researching permits for a similar animal, the process for goat ownership follows a comparable pattern of application, inspection, and compliance review, even though goats aren’t classified as exotic wildlife.

Key Insight: The permit application typically requires details on housing, enclosure security, and species identification. Reviewers use this information to confirm the animal won’t pose an escape or public safety risk.

Local City or County Restrictions in Wyoming

A state permit clears the first hurdle, but it doesn’t guarantee your city or county will let you keep an iguana at your address. Municipal governments in Wyoming retain authority over zoning, animal control, and nuisance ordinances, and that authority operates independently of the Game and Fish Department’s permitting system.

HOA covenants add another layer many owners overlook. Even in a permit-friendly state like Wyoming, a homeowners association can restrict exotic animals through its own rules, regardless of what the Game and Fish Department allows. Before finalizing any purchase, check both your municipal code and any HOA documents governing your property.

Municipal ordinances covering unusual animals aren’t hypothetical in Wyoming. Towns across the state already regulate animal-related nuisances at the local level, similar to how some Wyoming municipalities address rooster crowing complaints through city noise and animal codes rather than state law. An iguana enclosure, escape risk, or odor complaint could trigger a similar local review, so a call to your city clerk or planning department is worth the ten minutes it takes.

Important Note: Wyoming does not maintain a single statewide database of city-level exotic pet ordinances. Contact your specific city or county government directly to confirm local rules before applying for your state permit.

Can You Own Other Reptile Species Alongside an Iguana in Wyoming

Wyoming’s Chapter 69 permit system applies to cold-blooded wildlife broadly, not just iguanas, so owning multiple reptile species alongside your iguana is possible but each animal still needs to clear the same review. Native reptiles and exotic reptiles are treated differently under the rules, and that distinction matters if you’re building out a multi-species collection.

For wildlife actually taken from within Wyoming, the state’s nongame wildlife regulation carves out an exception: all amphibians and reptiles not specifically referenced in the regulation’s protected list may be taken for personal use without a permit. That exception covers native Wyoming species like the ones described in guides to Wyoming’s native snakes, or questions about whether coral snakes or the green snake occur in the state. It does not extend to imported, non-native reptiles like an iguana, which still require the standard possession permit regardless of how harmless the species is.

Venomous and potentially dangerous reptiles face a much higher bar than an iguana ever would. State law summaries make this distinction explicit: a permit for potentially dangerous animals, including venomous reptiles and snakes such as Gila monsters, coral snakes, cobras, and vipers, may be issued only after a clear showing that certain criteria have been met, and potentially dangerous species shall not be kept as pets. An iguana, by contrast, is non-venomous and generally treated as a standard exotic pet once permitted. If you’re curious about seasonal reptile activity while planning your collection, it also helps to know when Wyoming’s native snakes emerge, since that timing can affect outdoor enclosure security for any reptiles you keep.

Penalties for Illegal Iguana Ownership in Wyoming

Keeping an iguana in Wyoming without the required permit puts you in violation of the state’s wildlife possession rules, and the consequences extend beyond a simple warning. Wyoming Game and Fish wardens have authority to enforce Chapter 69 and the broader exotic species statute, and violations of Game and Fish Commission regulations are generally treated as misdemeanor offenses under state law.

Beyond legal penalties, an unpermitted animal is also at risk of confiscation. Because the permit system exists specifically to track exotic wildlife entering the state, an iguana discovered without proper documentation can be seized by wildlife officials regardless of how well it’s been cared for. This is one of the more overlooked risks compared to, say, researching Wyoming’s genuinely dangerous animals, where the concern is public safety rather than paperwork.

Ongoing compliance matters too, not just the initial application. As noted earlier, permit holders remain bound by all conditions of the permit issued, and any applicable Wyoming statutes, Commission regulations, federal statutes, county and municipal rules or ordinances. Letting a permit lapse, violating enclosure requirements, or ignoring a local ordinance can jeopardize your standing even after initial approval.

Important Note: Exact fine amounts and citation classifications for unpermitted wildlife possession can change and vary by circumstance. Contact the Wyoming Game and Fish Department directly for the current penalty structure before assuming what a violation might cost.

Getting the permit right from the start is far simpler than dealing with enforcement after the fact. If you’re still deciding which iguana species fits your setup, reviewing the differences between common iguana varieties before you apply can help you choose an animal that matches both your care capabilities and Wyoming’s permitting expectations.

Owning an iguana in Wyoming comes down to three things: securing the state permit, confirming your local ordinances allow it, and keeping your paperwork current for as long as you have the animal. None of those steps are especially difficult, but skipping any one of them turns what should be a straightforward hobby into a legal headache. Start with the Wyoming Game and Fish Department’s application process, check in with your city or county government, and you’ll be on solid ground before your iguana ever arrives home.
