A black cat is a domestic cat with black fur that may be a mixed or specific breed. The Cat Fanciers' Association (CFA) recognizes 22 cat breeds that can come with solid black coats. The Bombay breed is exclusively black. All-black fur pigmentation is slightly more prevalent in male cats than female cats. Their high melanin pigment content causes most black cats to have yellow (golden) eyes (irises). ==Coat== Any cat whose fur is a single color, including black, is known as a "solid" or "self". A "solid black" cat may be coal black, grayish black, or brownish black. Most solid-colored cats result from a recessive gene that suppresses the tabby pattern. Sometimes the tabby pattern is not completely suppressed; faint markings may appear in certain lights, even on a solid black cat. A cat having black fur with white roots is known as a "black smoke." Black cats can also "rust" in sunlight, the coat turning a lighter brownish shade.〔 In addition to the Bombay, the Cat Fanciers' Association allows solid black as a color option in 21 other breeds. The color description for those breeds is: :''Black'': dense coal black, sound from roots to tip of fur. Free from any tinge of rust on the tips. Nose leather: black. Paw pads: black or brown. The exceptions are: *Oriental – ''Ebony'': dense coal black. Free from any tinge of rust on tips or smoke undercoat. Nose leather: black. Paw pads: black or brown. *Sphynx – ''Black'': black. One level tone from nose to tip of tail. Nose leather: black. Paw pads: black or brown. *Ragamuffin – Although black is not specifically mentioned, the standard allows for "any color, with or without white," so technically speaking, an all-black Ragamuffin would be allowed under the breed standard. 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「Black cat」の詳細全文を読む スポンサード リンク
