An exotic pet is a rare or unusual animal kept as a pet, or an animal kept as a pet which is not commonly thought of as a pet.

The definition is an evolving one; some rodents, reptiles, and amphibians have become firmly enough established in the world of 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, or fish as "exotic".

An animal sanctuary is a facility where animals are brought to live and be protected for the rest of their lives. Unlike animal shelters, sanctuaries do not seek to place animals with individuals or groups, instead maintaining each animal until his or her natural death. In some cases, an establishment may have characteristics of both a sanctuary and a shelter; for instance, some animals may be in residence temporarily until a good home is found and others may be permanent residents. The mission of sanctuaries is generally to be a safe haven, where the animals receive the best care that is possible for the sanctuary's means. Animals are not bought, sold, or traded, nor are they used for animal testing. The resident animals are given the opportunity to behave as naturally as possible in a protective environment.

What separates a sanctuary from other institutions is the philosophy that the residents come first. In a sanctuary, every action is scrutinized for any trace of human benefit at the expense of non-human residents. Sanctuaries act on behalf of the animals, and the caregivers work under the notion that all animals in the sanctuary, human and non-human, are of equal importance.

A sanctuary is not open to the public in the sense of a zoo; that is, the public is not allowed unescorted access to any part of the facility. A sanctuary tries not to allow any activity that would place the animals in an unduly stressful situation.

One of the most important missions of sanctuaries, beyond caring for the animals, is educating the public. The ultimate goal of a sanctuary should be to change the way that humans think of, and treat, non-human animals.

There are several national and international organizations that have taken the responsibility of supervising numerous systems of non-profit animal sanctuaries in order to provide a general system for sanctuaries to follow. Among them, The American Sanctuary Association monitors and aids in various facilities to care for exotic wildlife. Their accredited facilities conform to high standards and a rigid application processes to ensure that the animals under their care are avidly cared for and maintained.
