Pet

A pet is an animal kept for companionship and enjoyment or a household animal, as opposed to livestock, laboratory animals, working animals or sport animals, which are kept for economic or productive 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, 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, that are brought to visit confined humans. Walking a dog can provide both the owner and the dog with exercise, fresh air, and social interaction.

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 showed that dog-owning households outnumbered those owning cats, but that the total number of pet cats was higher than that of dogs.Combined reptiles are the next popular followed by birds then horses.


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 neutered. 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.

Health risks that are associated with pets include:

• Aggravation of allergies and asthma caused by dander and fur or feathers
• Falling injuries. Tripping over pets, especially dogs, causes more than 86,000 falls serious enough to prompt a trip to the emergency room each year in the United States. Among elderly and disabled people, these falls have resulted in life-threatening injuries and broken bones.
• Injuries, maulings and sometimes deaths caused by pet bites and attacks
• Disease and/or parasites due to animal hygiene problems or lack of appropriate treatment (faeces and urine)
• Stress caused by behaviour of animals
• Fear or distress from animal presence or behaviour
• Spread of diseases like the fatal rabies when not properly taken care of.
