A cat can hear very high sounds with his ears. He can rotate his ears independently of each other in the right direction to correctly locate the prey or the danger. The hearing organ also contains a sensitive balance organ, which allows the cat to detect and adjust changes in direction and speed immediately. As a result, a cat can maintain its balance and turn around at lightning speed when falling. In most cases, a cat actually ‘lands on its paws.’
Cats with a completely white coat are likely deaf. There seems to be a relationship between the white coat and the color of the eyes. It is not allowed to breed with deaf cats in many cat societies, nor to use them in a show.
To demonstrate that the animal is not deaf, a so-called BAER-test (Brainstem Auditory Evoked Response) can be done at a specialized veterinarian.
