Are All White Cats With Blue Eyes Deaf

Not all blue-eyed white cats are deaf but many of them are.

Are all white cats with blue eyes deaf. Cornell University cites a study that found that 17 to 22 percent of white cats with non-blue eyes were born deaf. White cats with blue eyes often suffer from a genetic defect that causes their cochlea a vital organ within the inner ear to degenerate shortly after birthWhite cats with eyes of other colours can usually hear. The percentage rises to 40 percent if the cat has one blue eye while upwards of 65 to 85 percent of all-white cats with both eyes blue are deaf.

No not all white cats carry the W D gene and associated deafness. So why do all-white cats born with blue eyes experience deafness. 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.

Some white cats have blue eyes but not all. All-white cats born with one blue eye experience congenital deafness in 40 of kittens while kittens born with two blue eyes have an 85 chance of being born deaf. In fact only 85 of white cats are born with blue eyes while the rest of the white cats are born with brown eyes or some other color.

Some of these cats are deaf in only one ear. This gene can suppress and block other potential colors thus. NO not all pure white cats with blue eyes are deaf however.

However a lot of white cats with blue eyes are. The health problem occurs due to the different genes. The percentage rises to 40 percent if the cat has one blue eye while upwards of 65 to 85 percent of all-white cats with both eyes blue are deaf.

Also when a cat is a kitten we may not be able to determine if they are deaf since they are already developing. As we have mentioned previously not all white cats with blue eyes are prone to deafness. Interestingly most white cats regardless of eye color exhibit a special kind of deafness.
