In recent years, cats have become more and more popular as pets, especially those with blue eyes. There are rumors in the market that all these blue-eyed kittens are deaf. This statement is wrong. It can only be said that some white-haired cats are more likely to be deaf, but some breeds of cats are marked by beautiful blue eyes.
First, blue-eyed cats are deaf
The ancestors of blue-eyed cats are angola cat and Persian cats, which can be native cats or breed cats. The oldest long-haired cat in the world, angola cat, Turkey, is a white cat with blue eyes. Cat's hearing is very sensitive, and its function of locating sound and adjusting the balance of the body by the inner ear are better than that of people. Unfortunately, some white cats' unique blue eyes are related to deafness, but not all white cats with blue eyes are deaf, and the proportion of white cats with blue eyes is high.
The occurrence of congenital deafness's syndrome is mainly caused by gene abnormality on autosome, which is probably related to genetic factors. However, cats with congenital deafness's disease can't really "hear" any sound. They can still "hear" some sounds, but only through the meat pads under the paws of their limbs, not with their ears. Deafness rarely affects the cat's balance function. Although the cat with blue eyes can't hear, its sense of touch and other senses are more sensitive. Combined with normal vision, the deaf cat can also grow and develop very healthily. You can try shaking the bell from behind to see if the cat responds. If it doesn't, it may be deaf. But don't abandon it, and do sterilization, don't pass on this gene.
