Bicolor cat

A bicolor cat has white fur combined with fur of some other colour, for example black or tabby. There are various patterns of bicolor cat. These range from Van pattern (colour on the crown of the head and the tail only) through to solid colour with a throat locket. The tuxedo pattern is one of many possible bicolor patterns.

Where there is low-to-medium grade white spotting limited to the face, paws, throat and chest of an otherwise black cat, they are known in the United States as a tuxedo cat. High grade bicolor results in Van-pattern cats. There are many patterns between such as cap-and-saddle, mask-and-mantle and magpie (more randomly splashed). Bicolors are found in many breeds as well as being common in domestic longhair cats and domestic shorthair cats.

Solid color bicolor cats occur because there is a white spotting gene present along with a recessive allele of the agouti gene, which evens out the usual striped pattern of the colors of the coat. In contrast, tabby cats have an agouti gene that produces striping of the coat. The Abyssinian has agouti (ticked tabby) fur, giving the appearance of even colour with color-banded hairs.

White spotting can also occur with any of the tabby patterns, resulting in tabby-and-white bicolors. Colorpoint (Himalayan pattern) cats can have bicolor points although this variation is not recognised for exhibition. The body markings of bicolor colorpoints become clearer with age as the body fur of colorpoint cats darkens as the cats grow older and the white patches become more visible.

Tuxedo cats

A tuxedo cat is a bicolor cat with a white and black coat. The derivation of the term tuxedo cat is self-explanatory, as the animal appears to be wearing the type of black tie formal wear commonly known in the United States and Canada as a tuxedo. Most tuxedo cats are also black mask cats, a common name for felines who, due to their facial coloration, look as if they are wearing a black mask over their eyes, and often over their entire head. To be considered a true tuxedo cat, the feline's coloring should consist of a solid black coat, with white fur limited to the paws, belly, chest, throat, and often the chin, although many tuxedo cats appear to sport goatees, due to the black coloration of their mandible -- that is, the lower jaw and chin.
