White Cats With Blue Eyes Are Usually Deaf
No this is not always the case.
White cats with blue eyes are usually deaf. Not all white Cats are Deaf. Interestingly if a white cat with one blue eye is deaf in only one ear that ear will invariably be on the same side of the head as the blue eye. The common belief is that black and white cats are unique in that they have completely different-colored eyes.
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. A cat with an extreme form of the white-spotting gene may have more-or-less the same coloring maybe a few blond or gray hairs but is no more likely to be deaf than any other cat. The blue eyes in a piebald or epistatic white cat indicates a lack of tapetum.
Overall statistics indicate that. Why are white cats with blue eyes usually deaf. Albino cats are not linked to deafness.
Overall deaf cats with white coat colour and one or both blue eyes make up around about 1-15 of the total cat population. For those cats with other colored eyes only 10-20 are deaf. 40 percent of white cats with one blue eye were deaf.
