There are complications for cats suffering from ear mites. After being infected by ear mites, if the ear mites or ear mite secretions are not removed in time, it will cause otitis media or hearing impairment. Therefore, after a cat is diagnosed with ear mite infection, pet owners should promptly clean the ear mites and their secretions in the cat's ears, and use drugs to kill ear mites. If there is inflammation later, anti-inflammatory drugs should also be used.
