Causes of heavy bleeding in cat ears:

1. Injury from fighting. Having more than one pet in the home may result from arguments with other pets. Even when not in danger of fighting, cats are susceptible to bruises and knocks when playing alone.

2. Ear mite infection. Itching occurs when there are parasites in the ears, such as ear mites, and blood in the cat's ears is formed when the cat scratches.

3. Fungal infection. It can be caused by fungal or bacterial infections as well as skin diseases, which can also cause cats to feel itchy.

4. Secondary otitis media. Ear mites, bacterial and fungal infections may also cause secondary otitis media in cats. Sick cats will have strong itching and often scratch their ears with their limbs.

Treatment methods for bleeding in cat ears:

1. Isolate and clean. Because ear mites can be spread back and forth between animals, if you have other small pets at home, when you find that a cat has ear mites, you should isolate the cat separately, and then do a good job of cleaning and sanitation, and do indoor cleaning. Wipe and clean the environment and items used by cats to keep the environment dry and ventilated.

2. Treatment of the affected area. Use cotton dipped in some physiological saline to gently wipe the bleeding areas of the cat's ears to wipe away the blood clots. Then dip a cotton swab in some Mengwei ear drops and help the cat wipe the earwax from the outer auricle. Next, you can aim at the cat. Drop a few drops of ear cleaning solution into the inner ear canal, quickly cover the cat's ears for a moment and then release.

3. Supplement nutrition. Add some nutritional supplements to the daily staple food, such as boiled chicken breast, beef, fish and other meats, or nutritious fruits and vegetables. You can also feed your cat nutritional paste when needed.
