The Persian cat is a long-haired breed of cat characterized by its round face and short muzzle. In Britain, it is sometimes called the Longhair or Persian Longhair. It is also known as the Shiraz or Shirazi, particularly in the Middle East. The first documented ancestors of the Persian were imported into Europe from Persia around 1620.〔(【引用サイトリンク】title=persian cat Archives - Breed Guide )〕 Recognized by the cat fancy since the late 19th century, it was developed first by the English, and then mainly by American breeders after the Second World War. Some cat fancier organizations' breed standards subsume the Himalayan and Exotic Shorthair as variants of this breed, while others treat them as separate breeds. The selective breeding carried out by breeders has allowed the development of a wide variety of coat colors, but has also led to the creation of increasingly flat-faced Persians. Favored by fanciers, this head structure can bring with it a number of health problems. As is the case with the Siamese breed, there have been efforts by some breeders to preserve the older type of cat, the ''traditional breed'', having a more pronounced muzzle, which is more popular with the general public. Hereditary polycystic kidney disease is prevalent in the breed, affecting almost half the population in some countries. The placid and unpretentious nature of the Persian evinces a propensity for apartment living. It has been the most popular breed in the United States for many years but its popularity has seen a decline in Britain and France. ==Origin== It is not clear when longhaired cats first appeared, as there are no known long-haired specimens of the African wildcat, the ancestor of the domestic subspecies. There were claims in the 19th century that the gene responsible for long hair was introduced through hybridization with the Pallas cat, but research in the early 20th century refutes this theory. The first documented ancestors of the Persian were imported from Khorasan, Persia, into Italy in 1620 by Pietro della Valle, and from Angora (now Ankara), Turkey, into France by Nicholas-Claude Fabri de Peiresc at around the same time. The Khorasan cats were grey coated while those from Angora were white. From France, they soon reached Britain. Longhaired cats were also imported to Europe from Afghanistan, Burma, China and Russia. Interbreeding of the various types was common, especially between Angoras and Persians. Recent genetic research indicates that present day Persians are related not to cats from the Near East but to cats from Western Europe. The researchers stated, "Even though the early Persian cat may have in fact originated from ancient Persia, the modern Persian cat has lost its phylogeographical signature." 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Persian cat」の詳細全文を読む スポンサード リンク
