A rare predominantly black cat with odd 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 solid white) [3] or the white spotting gene (which is the gene responsible for bicolour coats) [4] prevents melanin granules from reaching one eye during development, resulting in a cat ...
[2] [4] [6] [7] The syndrome usually appears in cats after they've reached maturity, with most cases first arising in cats between one and five years old. [1] [2] [4] The condition is most commonly identified by frantic scratching, biting or grooming of the lumbar area, generally at the base of the tail, and a rippling or rolling of the dorsal ...
Human eyes have three types of cones: red-sensing, green-sensing and blue-sensing. Feline eyes also contain the same color-sensing cones as humans , but this doesn't mean our visions are the same ...
Domestic cat with complete heterochromia, also referred to as an odd-eyed cat. Eye color, specifically the color of the irises, is determined primarily by the concentration and distribution of melanin. Although the processes determining eye color are not fully understood, it is known that inherited eye color is determined by multiple genes ...
Unlike we humans, cats don't have cones that are sensitive to red wavelengths — that means that they lack the light-sensitive pigments at the back of their eye that enable them to see red.
White cats having one blue and one other-colored eye are called "odd-eyed" and may be deaf on the same side as the blue eye. [16] This is the result of the yellow iris pigmentation rising to the surface of only one eye, as blue eyes are normal at birth before the adult pigmentation has had a chance to express itself in the eye(s).
Our pets can be entertaining and do ridiculous things, and black-and-white cat Vik is no exception. His favorite thing to do is chase a red laser dot, and he never gives up on eventually catching it.
Deafness can occur in white cats with yellow, green or blue irises, although it is mostly likely in white cats with blue irises. [4] In white cats with one blue eye and one eye of a different color (odd-eyed cats), deafness is more likely to affect the ear on the blue-eyed side. [1] Approximately 50% of white cats have one or two blue eyes. [5]
