Will cats with different pupils have deaf ears? In fact, cats with heteropupils will not be deaf in both ears, because they have one normal ear and the other ear may have some defects, but will not affect their hearing.

The cats with different pupils may not be deaf in both ears, but it is said that most cats with different pupils have problems with their ears. Some cats with different pupils cannot hear one ear, and some cats with different pupils have deaf in both ears, which is a congenital disease that cannot be cured. If you are not sure whether your cat has deaf ears, it is recommended to go to a pet hospital for a hearing test. The scientific name of heteropupil is heterochromia, which belongs to a physical abnormality.   This symptom does not have any impact on vision, but it can cause hearing impairment. And the proportion is still very large. Basically half of the cats with different pupils have hearing problems, such as deafness in both ears or both ears.

Most of the cats with different pupils are white cats, and a few are other fur colors. The color combination types of different pupil eyes are usually blue on one side and yellow, brown, green, orange on the other side. As for why it appears frequently in white cats, it is due to congenital genetic inheritance, which leads to different eyes of cats. This situation occurs because of pigments, and pigments are determined by genes. This is a very normal phenomenon, just like the three-cat cats are generally female cats. In addition to the big white cats, different pupils are often seen in Persian cats, Thai royal cats, and oriental shorthair cats.
