Some states prohibit the possession of all wild or exotic animals—but most states only limit possession to certain types of wild or exotic animals. These state statutes often make exceptions for people and organizations that possess exotic animals for exhibition or scientific or educational purposes. Most states require a permit, license, or registration to possess certain wild animals. And many counties and cities also have laws and regulations that prohibit or limit the possession of wild animals.

In Nevada, the possession of wild or exotic animals is regulated by both state statutes and local ordinances. Nevada does not have a comprehensive state law that bans the ownership of all exotic or wild animals. Instead, it restricts the ownership of certain species under Nevada Administrative Code (NAC) 503.140, which requires permits for the possession of wildlife. The state generally allows ownership of exotic animals like elephants, primates, wolves, and some species of big cats, but individuals must obtain a permit for wild animals classified as 'dangerous' under NAC 503.110. These permits are typically issued for exhibition, educational, or scientific purposes. Additionally, Nevada Revised Statutes (NRS) 574.360 prohibits the possession of dangerous wild animals unless specific conditions are met. It's important to note that local jurisdictions within Nevada, such as counties and cities, may have their own regulations and may be more restrictive than state law. For example, Clark County has its own set of ordinances regarding the possession of exotic animals. Therefore, it is crucial for individuals to check with both state and local regulations before acquiring an exotic or wild animal in Nevada.
