Terminology

Dogs and cats are often considered "small animals", while horses, cattle, sheep, and similar are considered "large animals". "Exotics" include birds, squirrels, and reptiles.

Local restrictions

Many cities and towns have local ordinances limiting the number of pets a person may have, and may also restrict or forbid certain pets (such as fowl or exotics). Certain breeds of dog, such as pit bulls and rottweilers, are banned in some places. Dog/other canid/wolf mixes are also banned in some places.

The cities of Berkeley, California and Boulder, Colorado have passed laws stating that people who have pets do not "own" them; rather, they are the pet's "guardian."

Condominium associations and rental properties often ban animals^{[citation needed]} because of the smells and noise the animals create.
