Deafness in white cats
The gene that makes a cat white can also affect the inner ear. So a white cat is sometimes born deaf, in one or both ears. White cats with blue eyes have the highest chance; an odd-eyed cat is sometimes deaf only on the blue-eyed side. Coloured Angoras do not have this extra risk. A deaf cat usually lives well indoors: you get its attention with a wave or a touch.
How it is found: A hearing test (BAER) of white kittens. There is no DNA test.
