Owners can purchase cat-specific ear cleaning liquid and ear mite removal liquid to clean their cats. First, drop the ear cleaning liquid into the cat’s ears, rub it for a few times, and then use a wet tissue to wipe the inside of the ears; or directly use soaked ear cleaning liquid. Use cotton swabs of ear cleaning solution and gently clean the ears. Cats’ ears are prone to bacteria and mites, so they need to be cleaned regularly by owners.
