Exotic pet laws in Wyoming

Ch. 69 § 8(d); 50 CFR 17.11

An importation/possession permit shall not be issued for importation or possession of the live cold-blooded wildlife in this section, except as otherwise specified. ... (d) Endangered and threatened wildlife listed in 50 CFR 17.11.

50 CFR 17.11 lists the American alligator as threatened by similarity of appearance, and § 8(d) bars a permit for anything on that list, threatened as well as endangered, so the free reptile clause in § 10(a)(i) does not reach it.

How this rule works: Section 10(a)(i) is the sentence that matters for reptile keepers: amphibians and reptiles not listed in Section 8 or 9 need no permit at all.

Ch. 10 § 11(a); Wyo. Stat. § 23-1-101(a)(xii)(A)

There shall be no private ownership, private importation or private possession of live big or trophy game animals, except as otherwise specified in this regulation.

The black bear is a "trophy game animal" by statute, and § 11(a) bars private ownership of trophy game outright.

How this rule works: Two closed lists do the work. Domestic animals and domesticated animals are both defined by enumeration, with the phrase for the purpose of this regulation, only the following animals are considered domestic. Anything on neither list is wildlife, and Section 13(d) leaves it to a permit that may be authorized upon approval.

An importation/possession permit shall not be issued for importation or possession of the live cold-blooded wildlife in this section... (a) Injurious wildlife listed in 50 CFR § 16.

Ambystoma mexicanum is inside the same federal genus listing, so Wyoming will not issue a permit. Section 8 is absolute: it does not offer a permit route, it forecloses one.

The mountain lion is a "trophy game animal" by statute, and § 11(a) bars private ownership of trophy game outright, the black bear's position. Federally, the Big Cat Public Safety Act of 2022 (16 U.S.C. § 3372(e)) bars any person outside a licensed exhibitor, sanctuary or state institution from breeding or possessing a cougar unless the animal was born before December 20, 2022, and registered with the U.S. Fish and Wildlife Service within 180 days, so no new pet is lawful anywhere in the country whatever the state rule says.

Wyoming adopts the federal injurious wildlife list, and the green anaconda is on it, so no permit may issue, the Burmese python's position. Federally, the green anaconda has been injurious wildlife under the Lacey Act since 2015 (50 CFR 16.15(a)), which bars importing one into the country or shipping one to Hawaii or a territory; USARK v.

Wyoming would otherwise treat a lion like a serval, under the discretionary permit in § 13(d), but § 11(b)(xv) bars a permit for any animal on the federal endangered and threatened list, and 50 CFR 17.11 has the lion listed in two parts, Panthera leo leo as endangered and Panthera leo melanochaita as threatened. Because the bar takes in threatened as well as endangered, either subspecies is caught. Federally, the Big Cat Public Safety Act of 2022 (16 U.S.C. § 3372(e)) bars any person outside a licensed exhibitor, sanctuary or state institution from breeding or possessing a lion unless the animal was born before December 20, 2022, and registered with the U.S. Fish and Wildlife Service within 180 days, so no new pet is lawful anywhere in the country whatever the state rule says.

Every nonhuman primate is on the list for which a permit "shall not be issued", so a ring-tailed lemur has no route. The lemur family is also federally endangered, which § 11(b)(xv) bars separately. Lemur catta is on CITES Appendix I, which bars commercial international trade, so a pet lemur here can only come from captive breeding inside the country, and the whole family Lemuridae is listed endangered under the Endangered Species Act (50 CFR 17.11).

Wyoming would otherwise treat a tiger like a serval, under the discretionary permit in § 13(d), but § 11(b)(xv) bars a permit for any animal on the federal endangered and threatened list, and 50 CFR 17.11 has the tiger listed endangered wherever found.

An importation/possession permit shall not be issued for importation or possession of the live cold-blooded wildlife in this section... (a) Injurious wildlife listed in 50 CFR § 16.

Wyoming adopts the federal injurious wildlife list wholesale, and 50 CFR 16.14 covers every species in the genus Ambystoma. That makes the tiger salamander one of the few animals Wyoming will not permit at all, and the ban follows from a federal disease rule about Batrachochytrium salamandrivorans rather than from anything Wyoming decided about salamanders.

Ch. 10 §§ 2(z), 3, 13(d)

"Warm-Blooded Wildlife" means every live wild mammal and bird, their viable gametes (eggs and sperm), fertilized eggs, or any hybrid (including hybrids between wildlife and wildlife, and hybrids between wildlife and domestic or domesticated animals) or any transgenic product thereof.

Wyoming defines warm-blooded wildlife to include "hybrids between wildlife and domestic or domesticated animals" in terms, and a Bengal, the Asian leopard cat crossed with the domestic cat, is that hybrid. Section 3 requires a permit before importing or possessing any live warm-blooded wildlife; the leopard cat is on neither the Section 11 prohibited list nor the domestic list; and Section 13(d) leaves it to a permit that "may be authorized upon approval", which is discretion rather than entitlement. The pull the other way is § 2(i), whose domestic animal definition also mentions "any hybrid" of the domestic populations and lists cat (Felis catus). But that list is closed, names the mule separately where it means a hybrid, and § 2(z) is the clause written for exactly this cross. No generation line is drawn.

The bobcat is a "furbearing animal" by statute, and Chapter 10 § 13(a) requires a permit before importing or possessing one.

Venomous reptiles are the one group Chapter 69 pulls out of its free reptile clause, so a cobra needs an importation/possession permit and a veterinary certificate before import. § 9 lets the Department deny one where it would pose a risk to the state's wildlife resources.

Ch. 10 § 3; § 13(d)

Except as otherwise specified or exempted in this regulation, a permit from the Department is required prior to importation, possession, confinement or transportation of any living warm-blooded wildlife.

Wyoming is a closed-list state on the warm-blooded side and the southern flying squirrel is on none of the lists. It is not among the eighteen animals defined as Domestic at Ch. 10 § 2(i) or the twenty-four defined as Domesticated at § 2(j); it is not prohibited under § 11, whose only rodent entry is the order Rodentia from Africa; it is not a furbearer or a game bird under § 13; and § 16, the no-permit section, covers domestic and domesticated animals plus three classes of bird and no other mammal. So § 3 applies and § 13(d) is the route: "A permit may be authorized upon approval for other warm-blooded wildlife unless otherwise specified in this regulation." Recorded permit rather than banned because that clause is a grant of discretion rather than a bar, unlike Alaska, whose rule forbids issuing a pet permit at all. Wyoming's own flying squirrel is the northern, Glaucomys sabrinus; § 15 lets a Wyoming-caught nongame mammal be possessed without a permit while still requiring one to import the same animal.

May be authorized is not the same as shall be issued. The opossum is not a Wyoming furbearer, predatory animal or protected animal under § 23-1-101.

How this rule works: Two closed lists do the work. Domestic animals and domesticated animals are both defined by enumeration, with the phrase for the purpose of this regulation, only the following animals are considered domestic. Anything on neither list is wildlife, and Section 13(d) leaves it to a permit that may be authorized upon approval.

Ch. 10 §§ 12, 14(b); Wyo. Stat. § 23-1-101(a)(viii)(A)

The following wildlife may be possessed without a permit if captured in the state, but no importation is allowed. ... (b) Mammals declared as pests by W.S. 11-5-101 through W.S. 11-5-119, or animals defined in W.S. 23-1-101 as predatory animals.

The raccoon is a "predatory animal" by statute, which gives it an unusual split. Chapter 10 § 12 bars importing predatory animals, so one from a breeder in another state cannot come in, while § 14(b) lets a person keep one captured in Wyoming with no permit at all.

Domestic animals and domesticated animals are both defined by enumeration, with the phrase for the purpose of this regulation, only the following animals are considered domestic.

The red fox is named as a "predatory animal" in the statute, unlike the fennec. That means no importation under Chapter 10 § 12, but no permit needed under § 14(b) to keep one captured in Wyoming.

"Skunk" is on the statutory predatory animal list without a species limit. A skunk from out of state is barred at the border by Chapter 10 § 12, and one captured in Wyoming may be kept with no permit under § 14(b). A descented pet-trade skunk is always an import, so in practice that route is closed.
