A domestic long-haired cat is a cat of mixed ancestry – thus not belonging to any particular recognised cat breed – possessing a coat of semi-long to long fur.〔 Says 10% are long-haired.〕 Domestic long-haired cats should not be confused with the British Longhair, American Longhair, or other breeds with "Longhair" names, which are standardized breeds defined by various registries. Domestic long-haireds are the second most popular cat in the United States after the domestic short-haired;〔 one in ten of the ninety million cats in the US is a domestic long-hair.〔〔 Gives a figure of 95% short-haired.〕 Other generic terms are long-haired house cat and, in British English, long-haired moggie. In the cat fancy, and among veterinarians and animal control agencies, domestic long-haired cats may be classified with organisation-specific terminology (often capitalized), such as Domestic Longhair (DLH),〔 House Cat, Longhair (HCL), or Semi-Longhair Household Pet.〔 PDF version: http://www.wcf-online.de/WCF-EN/library/HHP_en_2010-01-01.pdf〕 Such a pseudo-breed is used for registry and shelter/rescue classification purposes. While not bred as show cats, some mixed-breed cats are actually pedigreed and entered into cat shows that have non-purebred "Household Pet" divisions. Show rules vary, and may permit "any eye colour, all coat colours and patterns, any coat length or texture, and any length of tail"〔 (i.e., anything at all, as long as the cat is well-proportioned and healthy) or may be more restrictive, e.g.: "The colours chocolate and cinnamon, as well as their dilution (lilac and fawn) are not recognized in any combinations...(t )he pointed pattern is also not recognized".〔 Domestic long-haireds come in all genetically possible cat colours including tabby, tortoiseshell, bi-coloured, and smoke.〔 Domestic long-haireds can have fur that is up to six inches long.〔 They can also have a mane similar to a Maine Coon's, as well as toe tufts and ear tufts.〔 Some long-haired cats are not able to maintain their own coat, which must be frequently groomed by a human or may be prone to matting.〔 Because of their wide gene pool, domestic long-haireds are not predisposed to any genetically inherited problems.〔 ==History== The domestic long-haired cat has been admired around the world for several centuries, particularly for its elegant looks and rugged nature. During the 16th century, the crusaders returning from the Holy Wars, having already brought back plague and pestilence from the East, also imported the first long-haired cats into Europe. In the mid-17th century, as the plague destroyed much of London's population, the cat made its first strides of recovery from centuries of persecution. Despite having been outlawed by the Roman Catholic church, during this time cats were encouraged as protectors from flea-carrying rats. How they developed in the first place is still a matter of speculation. The long coat may have been the result of a recessive mutant gene. When a long-haired cat is mated to one with a short coat, only short-haired kittens can result; however, their offspring when mated, can produce a proportion of long-coated kittens. Successive litters of early European long-haired cats produced more and more long-coated offspring, which were more likely to survive in the cooler European climates. By the year 1521, around the time they were first documented in Italy, the variety had become fixed after only a few generations.〔(【引用サイトリンク】title=Domestic Cat × Pallas's Cat )〕 In the late 18th century, Peter Simon Pallas had advanced the hypothesis that the manul (also known as Pallas's cat) might be the ancestor of the long haired domestic cat.〔 He had anecdotal evidence that established even though the male offspring would be sterile hybrids, the female offspring could again reproduce with domestic cats and pass on a small proportion of the Manul's genes. In 1907, zoologist Reginald Innes Pocock refuted this claim, citing his work on the skull differences between the Manul and the Angoras or Persians of his time.〔 This early hypothesis overlooked the potential for cross breeding within the Felidae family. For example, the Savannah Cat is a cross-breed between a DSH-Bengel and a wild African Serval—both of which have different skulls and evolutionary lineage. Furthermore, hybrid females in the related Panthera genus, such as ligers and tigons, have successfully mated in many documented cases, producing liligers and titigons. The first modern, formal breeds of long-haired cats were the Persian and the Angora (after Ankara, Turkey) and were said to have come from those two areas.〔 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「Domestic long-haired cat」の詳細全文を読む スポンサード リンク
