Tortoiseshell and calico cats are labeled X OX o, indicating O gene heterozygosity. Typically, the alleles are notated as an uppercase O for orange, or a lowercase o for not-orange. The primary gene for coat color (B), for the colors brown, chocolate, cinnamon, etc., can be masked by the co-dominant gene for the orange color (O), which is on the X chromosome and has two alleles: orange (X O) and not-orange (X o) that produce orange phaeomelanin and black eumelanin pigments, respectively. Tortoiseshell and calico coats result from an interaction between genetic and developmental factors. In the course of his studies he discovered that the rare tortoiseshell male is often sterile. Leonard Doncaster was the first to prove that tortoiseshell is the female heterozygote of orange and black, the corresponding male being orange. Tortoiseshell coloring can also be expressed in the point pattern, referred to as a tortie point. Not uncommonly there will be a "split face" pattern with black on one side of the face and orange on the other, with a dividing line running down the bridge of the nose. These patched tabbies are often called a tortie-tabby, a torbie or, with large white areas, a caliby. Occasionally tabby patterns of black and brown (eumelanistic) and red (phaeomelanistic) colors are also seen. Dilution genes may modify the coloring, lightening the fur to a mix of cream and blue, lilac or fawn the markings on tortoiseshell cats are usually asymmetrical. Typically, the more white a cat has, the more solid the patches of color. The size of the patches can vary from a fine speckled pattern to large areas of color. Tortoiseshell cats have particolored coats with patches of various shades of red, grey, and black, and sometimes white. Patterns Cat with a blue ("dilute") tortoiseshell coat A tortoiseshell with characteristic "split-face" pattern This pattern is especially preferred in the Japanese Bobtail breed, and exists in the Cornish Rex group. Tortoiseshell markings appear in many different breeds, as well as in non-purebred domestic cats. Those that are predominantly white with tortoiseshell patches are described as tricolor, tortoiseshell-and-white, or calico (in Canada and the United States). "Tortoiseshell" is typically reserved for multicolored cats with relatively small or no white markings. Tortoiseshell cats with the tabby pattern as one of their colors are sometimes referred to as torbies or torbie cats. The colors are often described as red and black, but the "red" patches can instead be orange, yellow, or cream, and the "black" can instead be chocolate, gray, tabby, or blue. Tortoiseshell cats, or torties, combine two colors other than white, either closely mixed or in larger patches. Male tortoiseshells are rare and are usually sterile. Like tortoiseshell-and-white or calico cats, tortoiseshell cats are almost exclusively female. That said, there are a few rename options on here.Īnd I stopped reading after Power of Three, well half-way through.Tortoiseshell is a cat coat coloring named for its similarity to tortoiseshell pattern. However, things noticeable as an infant would be allowed, since a kitten can be loud or quiet. Personlaity traits will not be added to this list, since I am of the belief that the kitten should only be named for its coat colour, size or circumstances of its birth. While some are concepts, these are somewhat uplifted cats who can seemingly see the colour red, so using words like serpent or zenith aren't too off the wall. The prefixes here are semi-traditional, meaning nothing manufactured by two-legs. The sacred names will not be the same based on people's idea of canon as well as how fan created clans behave. It does not mean that it is set for the four canon clans, and as such, each clan will have sacred names. However, it does fit clans in northern geographies (Europe and America mainly) better. This list is generalized, and not tailored to fit a particular clan.
