The ears of sphynxes are large, they do not have hairs on the inner surface, so ear grease constantly accumulates inside the shell. About once a week, it should be cleaned with a cotton pad soaked in a special lotion. Ear cleansing lotion can be purchased at a pet store. Cotton swabs are not used, as they can damage the inner ear. If the discharge in the ears has become too abundant, the cat shakes its head and tries to scratch its ears – this is an excuse to consult a veterinarian.
