Exotic Pet

The definition is an evolving one; some rodents, reptiles, and amphibians have become firmly enough established in the world animal fancy to no longer be considered exotic. Sometimes any unique or wild-looking pet (including common domestic animals such as the ferret and the domestic rat) is called an exotic pet. "Exotic" may also be used for a species which is non-indigenous to the owner's locale.
Many major pet stores and service providers (such as veterinary insurance carriers or online retailers) tend to classify any animal besides cats, dogs, small rodents, small birds or fish as "exotic".
