White Cats With Blue Eyes Are They Deaf

Full white kittens will either have blue or amber eyes or possibly one of each called odd eyes or heterochromia.

White cats with blue eyes are they deaf. Unless both ears are affected cats may never show any signs of hearing loss. It s believed that the ear closest to the oddly colored eye or both ears if both eyes are uniquely colored will be the ear with deafness. The variable penetrance of deafness and eye colour may be caused by interplay with other genes and or environmental factors. An estimated 40 percent of white cats with blue eyes are deaf which is high.

Domesticated cats with blue eyes and white coats are often completely deaf. Solid white cats with blue eyes are often deaf but their eyesight is completely normal. In white cats with mixed coloured eyes odd eyed cats it has been found that deafness is more likely to affect the ear on the blue eyed side. The deaf ear is usually on the same side as the blue eye.

A white cat with one blue eye has a 39 chance of at least partial deafness and a white cat with two blue eyes may have a 65 chance. Once again the brilliant scientist was right since between 56 and 90 of cats according to different studies with white coat and blue eye color are deaf from one or both ears. And 65 to 85 percent of white cats with two blue eyes were deaf. If 40 percent of these cats are deaf it means the majority 60 percent can hear.

Thus deafness is strongly linked to the white coat colour and blue eye colour but not all white cats or white cats with blue eyes are necessarily deaf. Deafness can occur in white cats with yellow green or blue irises although it is mostly likely in white cats with blue irises. 40 percent of white cats with one blue eye were deaf. In one 1997 study of white cats 72 of the animals were found to be totally deaf.

There is no truth that white cats with blue eyes are blind. White cats can have blue gold green or copper coloured odd eyes. And if the white cat has a different eye color for each eye heterochromia it will be deaf on the side where it has the blue eye. Not all white cats are deaf.

The same genetic factors that give white cats their snowy coats and unique eye colors can also cause total or partial deafness in many kitties. Felines with a single blue eye are often deaf in one hear usually the ear on the same side as their blue eye while two blue eyes make an ivory cat likely to suffer total deafness in both ears. Eye color in white cats also relates to the potential for deafness. White cats with blue eyes had a high probability.

Of white cats with one blue eye about 40 percent are deaf in at least one ear. First of all it can be said that not all white cats are deaf but they are more likely to be deaf since they carry the so called gene w white of white in english especially those that have one eye of each color or blue eyes. Still look at it this way.
