Black CatsEditA black cat is a domestic cat with black fur that may be a mixed or specific breed. The Cat Finacers Assosiation (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 mealain pigment content causes most black cats to have yellow (golden) eyes (irises).
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.
