Cats
that colour to the kittens.
Blue eyes also occur in white cats and are associated with the epistatic white (often called
dominant white) gene which is quite different from albinism because it masks an underlying
coat colour. The white spotting gene also affects eye pigment if there are white patches
around the eyes. White cats can have one or both eyes blue. The non-blue eye will be
whatever colour the breed standard requires for example in white Persians, the other eye is
vivid orange. In the randombred odd-eye white cats, the non-white eye might be green or
yellow or even a different shade of blue. For more on blue-eyed white cats White Cats, Eye
Colours and Deafness.
The Ojos Azules is characterised by cornflower blue eyes, but the mutation is linked to lethal
deformities if a kitten inherits 2 copies of the mutated gene. In this breed, the eye colour is
independent of the coat colour. Other blue eye mutations that are independent of coat colour
crop up from time to time
