Cats naturally love to be clean, and there is little need to help them deal with the details of hygiene.

Ear mites are a parasite that is unique to cats and dogs and cannot be transmitted to humans. However, if you have several cats in your home and one of them gets ear mites, other cats may not be immune to it. Ear mites infest the epidermis of the inner wall of a cat's ears and are invisible to the naked eye but can be seen through a microscope. It will secrete a dark brown paste-like substance, which will make the cat itchy. In severe cases, it will cause inflammation and infection, which must be treated.

Rub the outside a few times to spread the medicine evenly in the ear, 2-3 times a day.
