Deafness can be classified as either a complete or partial hearing loss. If your cat is deaf at birth (congenital), it will be apparent to you when the cat is still at a young age. Cats that have white hair and blue irises appear to be particularly prone to congenital deafness. Some of the breeds that tend to be at highest risk for congenital deafness are white Persians, white Scottish folds, Ragdolls, white cornish rex and Devon rex, white oriental shorthair, white Turkish angora, white Maine coone, and white manx.
You will need to give a thorough history of your cat's health, onset of symptoms, and possible incidents that might have preceded this condition, including any drugs that may have damaged the ear or caused a chronic ear disease. Early age onset usually suggests birth defects (congenital causes) in predisposed breeds.
On the other hand, brain disease is a slow progressive disease of the cerebral cortex, usually caused by senility or cancer – causing the brain to be unable to register what the ear can hear. Bacterial cultures and hearing tests, such as sensitivity testing of the ear canal, may also be used to diagnose any underlying conditions.
