Guinea pigs (also commonly called cavies after their scientific name) are rodents belonging to the family Caviidae and the genus Cavia. Despite their common name, these animals are not pigs, nor do they come from Guinea. They are originally native to the Andes, and while no longer extant in the wild, they are closely related to several species that are commonly found in the grassy plains and plateaus of the region. The guinea pig plays an important role in the folk culture of many indigenous South American groups, especially as a food source, but also in folk medicine and in community religious ceremonies.[1] Since the 1960s, efforts have been made to increase consumption of the animal outside South America.
Cavy Clubs and Associations dedicated to the showing and breeding of guinea pigs have been established worldwide. The American Cavy Breeders Association, an adjunct to the American Rabbit Breeders Association, is the governing body in the United States and Canada.
With the export of Guinea pigs to Europe in the 15th century, the goal in breeding shifted to focus on the development of appealing pets. To this end, various competitive breeding organizations were founded by fanciers. The American Cavy Breeders Association, an adjunct to the American Rabbit Breeders Association, is the governing body in the United States and Canada. The British Cavy Council governs cavy clubs in the United Kingdom. Similar organizations exist in Australia (Australian National Cavy Council) and New Zealand (New Zealand Cavy Club). Each club publishes its own Standard of Perfection and determines which breeds are eligible for showing. New breeds continue to emerge in the 21st century.
Though there many breeds of Guinea pig, with only a few breeds are commonly found off the show table as pets. Most Guinea pigs found as pets were either found undesirable by breeders or were bred to be good companions regardless of how well they meet the breed standard of perfection. The short hair, Abyssinian, Peruvian and Sheltie (aka Silkie) breeds are those most frequently seen as pets, and the former three are the core breeds in the history of the competitive showing of Guinea pigs. In addition to their standard form, nearly all breeds come in a Satin variant. Satins, due to their hollow hair shafts, possess coats of a special gloss and shine.
