Most states have specific laws governing the possession of dangerous wild animals, and the liability of landowners for injuries caused by wild animals on their property. Ferae naturae is a common law doctrine (created by judges in court opinions) meaning "animals of a wild nature or disposition," and traces its origins back to the Roman empire. Under the doctrine of ferae naturae, wild animals are presumed to be owned by no one specifically, but by the people generally.

In many states the rule of law has developed that a landowner cannot be held liable for the acts of indigenous wild animals occurring on his or her property unless the landowner has actually reduced the wild animals to possession or control, or introduced a non-indigenous animal into the area.

In Oklahoma, the possession of certain wild animals is regulated by the Oklahoma Wildlife Conservation Code, which requires permits for owning, breeding, or selling wildlife. The state has specific statutes that list the animals considered to be dangerous wild animals and the requirements for keeping them. Regarding liability for injuries caused by wild animals, Oklahoma follows the common law doctrine of ferae naturae, which means that landowners are generally not liable for injuries caused by wild animals native to the region unless the landowner has taken possession or control of the animal, or has introduced a non-native species that causes harm. This principle is based on the idea that wild animals are unowned and are the responsibility of the state or the people collectively. However, if a landowner's actions, such as maintaining artificial conditions that attract wild animals, lead to an injury, the landowner may be held liable under certain circumstances. It is important for landowners and those possessing wild animals in Oklahoma to understand these regulations and potential liabilities, and they may wish to consult with an attorney for specific legal advice.
