ferae naturae

Latin, meaning wild animals.  refers to animals considered to be wild. The common law divides animals into two categories: domesticated animals and wild animals (fera naturae). While owners may be liable for the acts of domesticated animals if they were negligent or had reason to know of specific propensities for danger, owners who possess or harbor wild animals will be strictly liable for injuries the wild animal causes. By comparison, an owner is not strictly liable for injuries of wild animals that are indigenous and wander freely on owner’s land.

Example:

Before he lost his zoo, Joe Exotic the Tiger King would be strictly liable for injuries any of his big cats caused.
