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 ...
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 ...
A black cat resting on a fence. A black cat is a domestic cat with black fur. They may be a specific breed, or a common domestic cat of no particular or mixed breed. Most black cats have golden irises due to their high melanin pigment content. Black cats are the subject of myth, legend, and superstition.
The reason that cats are seen as yōkai in Japanese mythology is attributed to many of their characteristics: for example, the pupils of their eyes change shape depending on the time of day, their fur can seem to cause sparks when they are petted (due to static electricity), they sometimes lick blood, they can walk without making a sound, their wild nature that remains despite the gentleness ...
Cats' eyes are largely similar to ours but with some fascinating differences, and one thing they have that we don't is a third, inner eyelid, called the nictitating membrane. When a cat blinks it ...
Sequencing of the agouti signalling peptide in the agouti gene coding region revealed a 2-base pair deletion in black domestic cats. These variants were absent in melanistic individuals of Geoffroy's cat, oncilla, pampas cat and Asian golden cat, suggesting that melanism arose independently at least four times in the cat family.

Black cats being bad luck is a myth that has persisted through the centuries. Find out the history and the truth to see if black cats are really evil or not.
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]
