The condition most commonly affects white cats, but may be found in a cat of any color, provided that it possesses the white spotting gene.[3]

Generally speaking, pedigreed cats tend to have more vivid and distinct eye pigmentations due to selective breeding. Odd eyes can be inherited from parents (genetic) or acquired due to certain illnesses, injuries, and medications. The reasons they see better in darkness than us, mere humans, are because 1) they have more rods (they can therefore detect more light than us) and 2) they have a tissue in the back of the eyes called tapetum lucidum.

Turkish folklore suggests that the eyes must be as green as the lake and as blue as the sky, and since 1817, the Turkish Angora (a pure white cat with blue and amber odd eyes) has been bred through a breeding program aiming to preserve and protect this trait.

In flash photographs, odd-eyed cats typically show a red-eye effect in the blue eye, but not in the other eye. This is due to the combined effect of the (normal) presence of a tapetum lucidum in both eyes and the absence of melanin in the blue eye. The tapetum lucidum produces eyeshine in both eyes, but in the non-blue eye a layer of melanin over the tapetum lucidum selectively removes some colors of light.
