 (color on the crown of the head and the tail only) through to solid color 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 or Billicat. 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

 has agouti (ticked tabby) fur, giving the appearance of even color 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 recognized for showing. 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.

Grades 1 - 10 of bicolor in cats

There are 10 identifiable grades of bicolor in cats, plus several patterns with their own names. The cat labelled "bicolor" is the preferred pattern in show-quality bicolor purebred cats.

A low-grade spotting black-and-white bicolor cat is often known as a "tuxedo cat" or a "Billicat". To be considered a tuxedo cat, its black coloring should be solid throughout, with white limited to the paws, belly, chest, throat, face, and possibly the chin: it should appear as if the cat were wearing a tuxedo

Another type of black-and-white bicolor cat is nicknamed "cow cat" or "moo cat" (for a perceived resemblance to Holstein cattle

) and includes the magpie, cap-and-saddle and mask-and-mantle patterns. A cow cat does not have the solid black "jacket" of the tuxedo cat. Instead, it has big black patches over a mostly white body, often with a black mask over the head. "Black Mask Cats" are so called because they look like they are wearing a black mask over their head. The Turkish Van

  • Seychellois Neuvieme - white with colored tail and head splashes (classic Van Pattern)
  • Seychellois Huitieme - white with colored tail and head splashes plus additional splashes of color on the legs
  • Seychellois Septieme - white with splashes of color on the legs and body in addition to those on the head and the colored tail.


This is high grade white spotting of types 9, 8 and 7 on the bicolor chart above.

Frequency in different breeds

This coloration is not restricted to a specific breed of cat, as it can be found in many different types of pure-breed as well as mixed-breed domestic cats. However, some breeds of cats are especially noted for having bicolor coats in their breed standards. These include the Turkish Van

Genetics of coat patterns

The basic colors and patterns of cat fur are defined by fewer than ten genes. Cats with white color in their coats are thought to have a mutant white-spotting gene that prevents the formation of coat color in patches over the cat's body. This gene has been investigated in several species, particularly mice, and is co-dominant
Dominance relationship

s into the developing hair follicles. The genetics of this pattern are not as well understood in cats but at least some of the genes involved in melanocyte migration and survival may play a role similar as in other animals.

Three genotypes possible with the S (white spotting) gene, with capital S standing for a wild-type copy and lower-case s standing for the mutant.
  • SS (two dominant alleles) results in high grades of white spotting (sometimes resulting in a solid-looking white cat or a white cat with just a few color hairs)
  • Ss (one dominant, one recessive allele) results in medium grades of white spotting
  • ss (two recessive alleles) results in solid color or low grades of white spotting (sometimes as little as a few white hairs)


The lack of tabby striping in bicolor cats is controlled by the agouti protein

 and thus prevents the formation of dark hair colors. In agouti cats the gene is turned on and off as the hair grows, producing hairs with alternating stripes yellow and black. In domestic cats, inactivation of the agouti gene by a deletion mutation causes all-black coat color.
