The reasons why cats always scratch their ears:
1. If a cat is infected with ear mites, it will scratch its ears if it itches. The owner needs to buy ear cleaning liquid in time to kill the mites. .
2. There are too many hairs on the cat’s ears. If fleas, lice, etc. are active around it, it will cause ear itching. The owner should deworm the cat in time.
3. If the cat is allergic to food, causing itchy skin and scratching its ears all the time, the owner needs to take the cat to the pet hospital for examination in time.

4. When a foreign object enters the cat's ear and the cat feels uncomfortable, it will tap or scratch the ear with its paws. Use tweezers to remove the foreign object in time.

5. If a cat has an ear injury due to a fight, and the wound is painful and uncomfortable, it will keep scratching its ears. If the injury is minor, the owner needs to clean and disinfect the cat's wound. If the injury is more serious, it needs to be sent to the hospital for treatment.
