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 ...
This amount varies strongly between individuals. People with blue eyes have relatively low melanin in the fundus and thus show a much stronger red-eye effect than people with brown eyes. Red-eye effect on dark brown eyes. The same holds for animals. The color of the iris itself is of virtually no importance for the red-eye effect. This is ...
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.

Cat behaviorist John Bradshaw explains to National Geographic that cats essentially treat us like they would other cats. "Putting their tails up in the air, rubbing around our legs, and sitting ...
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).
