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 Fact: date=December 2007 because of the smells and noise the animals create.

Pet popularity

Around 63 percent of all U.S. households (71.1 million) are pet owners, and more than half of these households have more than one animal . The two most popular pets in most Western countries have been cats and dogs. In the United States, a 2007-2008 survey shows that dog-owning households outnumber those owning cats, but that the number of pet cats is higher than dogs. Combined reptiles are the next popular followed by birds followed by horses.

According to a 2007-2008 Pet Owners Survey

In Canada the latest survey done by Colin Siren of Ipsos Reid it is estimated that there are 7.9 million cats and 5.9 million dogs in Canada. The survey also shows that 35% of Canadian households have a dog, while 38% have a cat, which is consistent with other surveys conducted around the world.

Overpopulation

main: Overpopulation in companion animals Animal protection advocates call attention to pet overpopulation in the United States. According to the Humane Society of the United States, 3-4 million dogs and cats are euthanized each year in the country and many more are confined to cages in shelters. This situation is created by nonneutered animals (spayed/castrated) reproducing and people intentionally breeding animals. A particularly problematic combination of economic hardship combined with a love of animals contributes to this problem in parts of the rural United States. In an average year, a fertile cat can produce three litters of kittens, with up to 4 to 6 kittens in each litter. Based on these numbers, one female cat and her offspring could produce up to 420,000 cats over a seven year period if not spayed or castrated. There are also major overpopulation problems with other pet species, such as birds and rabbits. Local humane societies, SPCAs, and other animal protection organizations urge people to neuter their pets and to adopt animals from animal shelters instead of purchasing them from breeders or pet stores.
