The dominant white spotting allele is like the dominant white allele, but this one only blocks the melanocytes from reaching certain areas of the skin. This gene will also cause blue eyes in your cat and deafness. The dominant white allele blocks melanocytes from reaching the skin, resulting in a pure white cat no matter what other color genes they have. If they get the recessive allele, it will prevent any white from showing in their fur. If they receive the dominant W, the coat can have white. The wild-type allele can be W/w and determines whether white is in the coat. Heterozygotes will have white paws but may also have other white patches. It’s a recessive gene, and homozygotes will have white paws. The Birman gloving allele is responsible for the white paws of many cats. It’s rare to get enough coverage of color with the correct pattern to get the name tuxedo, and most are Vans. The overall look resembles a man’s tuxedo. This pattern can have white paws as well. Tuxedo is a bi-color pattern that features an all-black cat with a bit of white on its chest. Tuxedo Image Credit: Mary Swift, Shutterstock A male cat born with an extra X chromosome may also produce this pattern in rare cases. Like tortoiseshell, only females can create this pattern normally. Calico cats also have a large amount of white fur, especially on their underside, which the tortoiseshell does not have. The calico features the same colors as a tortoiseshell, but the colors resemble patches instead of a blended or swirled coat. Calico Image Credit: Kristi Blokhin, Shutterstock While the tortoiseshell is not that rare among female cats, a male cat will require an extra X chromosome to produce this pattern, which makes finding one extremely rare. There can also be some white in the colors, but the white will be in small amounts without any large areas covered. Tortoiseshell is a tricolor pattern that features a mottled or swirled mixture of red and black or any of the diluted colors.

In this case, the pattern affects solid-colored cats and leaves the bottom 8th of the strands a white or cream color. ColorPoint PatternĪ post shared by Picasso Dreams smoke pattern is somewhat like the silver pattern and is a condition that leaves a part of the hair uncolored. Though not true albinos, these cats are extremely rare, and you will unlikely see one without contacting a professional breeder. These cats do not have the health concerns that albino cats have, and their eyes are the same as other cats. Cats that receive the correct combination of alleles will appear pure white, even if they have other color genes, because this condition blocks the pigment from reaching the skin. The white cat may look like an albino cat, but the color comes from the KIT gene we mentioned earlier. White Cat Image Credit By: vistawei, Pixabay Their skin can also suffer damage from the sun, especially around the nose and ears. These cats usually have the trademark albino blue eyes and must stay out of the sun to protect them. Most cats will get one of the alleles and present the ColorPoint pattern instead. Two recessive alleles in the C gene cause complete albinism, and it is extremely rare for cats to get both. A post shared by Odessa the Cat albino cat is the rarest of all coat types.
