Dogs, by nature a pack animal, can form very close bonds with other animals, including humans.

A pet or companion animal is an animal kept for companionship and enjoyment, as opposed to livestock, laboratory animals, working animals or sport animals, which are kept for economic reasons. The most popular pets are noted for their loyal or playful characteristics, for their attractive appearance, or for their song. Pets also generally seem to provide their owners with non-trivial health benefits;^[1] keeping pets has been shown to help relieve stress to those who like having animals around. There is now a medically-approved class of "therapy animals," mostly dogs, who are brought to visit confined humans. Walking a dog can provide both the owner and the dog with exercise, fresh air, and social interaction.

[edit] Domestication

Main article: Domestication

Cats in the Garden, by Chinese painter Mao Yi, 12th century; family pets in the Song Dynasty included watch dogs whose tails were often docked, long-haired cats for catching rats, cats with yellow-and-white fur called 'lion-cats' (who were valued simply as cute pets), and even crickets in cages.^[2][3] Cats could be pampered with items bought from the market such as 'cat-nests', and were often fed fish that were advertised in the market specifically for cats.^[2][3]

While in theory any animal might be a pet, in practice only a small number of species of mammals (especially dogs and cats) and other small animals, such as birds, fish, or lizards, are practical. One reason for this is that large animals are not able to fit inside small dwellings.

In general, a pet must either be small enough (or easily controlled) for his or her undesirable behavioral tendencies to be negligible, or the animal must be actually domesticable. Examples of the former are such animals as fish (including carnivorous ones such as piranha), chickens, invertebrates or small mammals.

A few animals are sufficiently capable of adapting to human interaction to be considered domesticable. Dogs ("man's best friend") are considered to be a classic example of domesticated animals normally suited to being pets. Domestic dogs are quite similar to wolves, but their physical form and behavior are characteristically different, more than mere differences in size, coat, or coloring. Behaviorally speaking, characteristic changes in dogs due to domestication include a prolonged infancy, increased playfulness, and increased barking. Wolves are far less playful and vocal.

Over the course of fifty years, Russian scientists also domesticated silver foxes, resulting in the Tame Silver Fox. While the number produced was extremely small, they have been sold as pets, and they prove that domestication of canids other than wolves is possible.

Many rodents—such as fancy rats, fancy mice, and Syrian hamsters—are commonly kept as household pets.

Such animals as reptiles are typically considered exotic pets. This may change in the future, as 'exotic' pet ownership is increasing rapidly. Some of these animals, such as green iguanas, large monitor lizards, and large birds, do not make suitable pets for the average person, as they require extensive housing and diet. They can also become quite aggressive if not regularly handled. Exotic mammals are also becoming increasingly more popular as pets. For example, the domesticated hedgehog has been selectively bred to the point where its physical characteristics no longer directly match its wild European and African counterparts.^{[citation needed]} Individuals have occasionally run into legal trouble for keeping large exotic pets, both in rural estates and urban apartments. A few years ago, New York Police Department officers arrested a man who had kept large cats and an alligator in a small Manhattan apartment ^[4] Many animal species are difficult to handle and cannot be pets for the general populace. Raptors, such as eagles and falcons, must be handled very carefully to avoid attacks on their handlers; the sport of falconry is to a large extent ways of avoiding such outcomes, and so they are not really pets in the sense meant here. Large cats cannot become pets, as they do not reliably restrain their impulses (although cheetahs are an exception and have been kept as pets in the past). Nor do the large bears, for similar reasons. Small monkeys can be human companions, but they are notoriously unable to defer their curiosity which leads to much destruction. Raccoons also fit this example. They adapt easily to almost any environment, but resist domestication. One the other hand, several of the ferret and otter varieties can be human companions.

A pet can be acquired from a pet store, animal shelter, a breeder, and from private transactions, typically due to the giving away of extra newborns after the birth of a litter. See also pet adoption. Because of environmental and public safety concerns, some pets are illegal in many areas.

[edit] Terminology

In veterinary medicine, dogs and cats are often considered "household" pets, while all other animals are grouped into either "farm animals" (such as horses, cows, or sheep) or "exotics" (including pocket pets, birds, and reptiles).^{[citation needed]}

[edit] 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).

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.

[edit] Pet popularity

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.^[5] Combined reptiles are the next popular followed by birds followed by horses, and finally, monkeys.

[edit] Overpopulation

The examples and perspective in this section may not represent a worldwide view of the subject. Please improve this article or discuss the issue on the talk page.

Animal protection advocates call attention to the pet overpopulation "crisis" 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 crisis 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.^[6] 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.

[edit] Effects of pets on their caregiver's health

[edit] Health benefits

Pets have the ability to stimulate their caregivers, in particular the elderly, giving people someone to take care of, someone to exercise with, and someone to help them heal from a physically or psychologically troubled past.^[7] Having a pet may help people achieve health goals, such as lowered blood pressure, or mental goals, such as decreased stress.^[8] There appears to be strong evidence that having a pet can help a person lead a longer, healthier life. In a study of 92 people hospitalized for coronary ailments, within a year, 11 of the 29 without pets had died, but only 3 of the 52 who had pets.^[7] A recent study concluded that owning a pet can reduce the risk of a heart attack by 2% and that pets are better than medication in reducing blood pressure.^{[citation needed]} Dogs which are trained into guide dogs can help persons with visual impairments.

[edit] Pets in long-term care institutions

Even pet owners residing in a long-term care facility, such as a hospice or nursing home, experience health benefits from pets. Pets for nursing homes are chosen based on the size of the pet, the amount of care that the breed needs, and the population and size of the care institution.^[7] Appropriate pets go through a screening process and, if it is a dog, additional training programs to become a therapy dog.^[9]

Different pets require varying amounts of attention and care; for example, cats have lower maintenance requirements than dogs.^[10]

[edit] Health risks

Health risks that are associated with pets include:

• Aggravation of allergies and asthma
• Injuries, maulings and sometimes deaths caused by dog bites and attacks
• Disease or parasites due to animal hygiene problems (feces and urine)
• Stress caused by behavior of animals
• Fear or distress from animal presence or behavior

[edit] Pets and allergies

Some people with allergies can have adverse reactions to animal dander and fur or feathers. Some people with asthma can have attacks triggered by these.
