![]() ![]() ![]() The differences in an odd-eyed kitten's eye colour might not be noticeable, except upon close inspection. Kittens Īs with some other newborn mammals, all cats are blue-eyed as kittens, and may change as the newborn ages. In the Japanese Bobtail, odd-eyed cats are most frequently found in calico individuals. However, odd-eyed cats are popular within several breeds, including Van cat, Turkish Van, Turkish Angora, Sphynx, Persian, Oriental Shorthair, Japanese Bobtail and Khao Manee. Odd-eyes are found in all domestic cats, and are not linked to a specific breed. A famous example of this case is the extinct Ojos Azules cat. These cats carry a dominant blue eye-gene, which is not linked to coat colouration. The odd-eye condition only rarely occurs in cats that lack both the dominant white and the white spotting gene. Approximately 15–40% of the solid white cats have one or two blue eyes. The odd-eyed colouring is caused when either the epistatic (recessive) white gene or dominant white (which masks any other colour genes and turns a cat completely white, solid white) or the white spotting gene (which is the gene responsible for bicolour coats) prevents melanin ( pigment) granules from reaching one eye during development, resulting in a cat with one blue eye and one green, yellow, amber, or brown eye. Genetics A rare predominantly black cat with odd eyes The condition most commonly affects solid white cats, but may be found in cats of any coat colour. There is also sectoral (partial) heterochromia, where two different colours occur within the same iris. This is a feline form of complete heterochromia, a condition that occurs in some other animals, including humans.
