Nuanyang Meow Home is a Douyin blogger. She has 2 cats. Hammer is a blue-eyed white cat with congenital deafness.

Just like humans have genetic diseases, cats also have some genetic diseases. Among blue-eyed and white cats, the incidence of congenital deafness is very high. In Darwin's Origin of Species, it is mentioned that most white-haired blue-eyed cats are born deaf.

Cat's Coat color, eye color, and congenital deafness are all genetically related. The congenital deafness syndrome in cats is mainly caused by genetic abnormalities in the autosomal body, which lead to one of the hearing organs - the organ of Corti, the cochlea The development of the spiral ganglia, etc., is incomplete, or even not developed at all, resulting in deafness.

There are some white cats around us with one yellow and one blue eyes, and the ear on the same side of the blue eye is usually deaf.
