You will agree with me that odd eyed cats are stunningly beautiful and unique!!
An odd-eyed cat is a cat with one blue eye and the other eye either green, yellow or brown.
These felines have a condition known as heterochromia, which occurs in some other animals as well , including humans. This condition most commonly affects white cats, but may be found in a cat of any color, that possesses the white spotting gene.
Heterochromia is common in British Shorthairs, Cornish and Devon Rex, Japanese Bobtails, Munchkins, Persians, Scottish Folds, Siamese, Sphynxes, Turkish Angoras and Turkish Vans breeds but can also occur in white cats of any breed.
In Acquired heterochromia, a loss of pigmentation in the iris happens because of either, inflammatory conditions, physical injuries or even certain medications
Interestingly white cats with one or more blue eyes have a higher incidence of congenital deafness, with the white gene occasionally causing degeneration of the cochlea, beginning a few days after birth.
If a white odd eyed kitten has any speck of another color, then the frequency of deafness is greatly diminished, even if the speck of coloration fades with maturity of the cat.
