Cat ear bleeding may be caused by trauma, ear mite infection, fungal or bacterial infection, secondary otitis media, tumors, etc. If there is obvious trauma to the cat's ears, it is more likely to be caused by trauma, and you need to help the cat deal with the trauma in time. However, if there is no obvious trauma to the cat’s ears, it is recommended to take the cat to the pet hospital for an ear endoscopy as soon as possible to confirm the cause and then provide symptomatic treatment.

　1. Trauma

The primary consideration for cat ear bleeding is trauma. Because cats are naturally more lively and active, during the process of beating and running, it is likely to cause skin damage or blood vessel rupture in the ear canal, leading to ear bleeding. In this regard, the owner can carefully check whether there is any trauma in the cat's ears. If so, the blood stains need to be cleaned with saline first, then disinfected with iodophor, and anti-inflammatory ointment can be applied at the same time.

　2. Infection with ear mites

When a cat is infected with ear mites, the ear mites crawl in the ear canal, causing itching in the ear canal, causing the cat to scratch frequently, leading to ear ulceration, and then ear bleeding. If it is an ear mite infection, you can also find a lot of black secretions in the cat's ear canal. At this time, you need to consult a pet doctor in time, follow the doctor's instructions, use mild ear canal cleaning solution to clean the cat's ear canal in time, and cooperate with instilling drugs to treat ear mites. Once the ear mites recover and the itching subsides, the ear canal damaged by scratching will gradually recover.

3. Fungal or bacterial infection

Fungal or bacterial infection can cause inflammation of the skin in the cat's ear canal, leading to redness, swelling, ulceration, etc. in the cat's ear canal, which can then cause bleeding in the cat's ear. In response to this situation, it is necessary to take the cat to the pet hospital for examination in time to confirm the specific cause and then treat it symptomatically.

4. Secondary otitis media

Ear mites, bacteria, and fungal infections may also cause secondary otitis media in cats. Cats with otitis media will often scratch their ears due to severe itching, resulting in ear abrasions and bleeding. At this time, treatment needs to be carried out according to the principles of anti-inflammation, anti-itching and disease removal. At the same time, you should also pay attention to regularly cleaning the dirt in the cat's ear canal, and wear an Elizabethan ring on the cat to prevent the cat from scratching due to itching.

5. Tumor

If there is a tumor in the cat's ear, the tumor will rupture and cause blood vessels to rupture and cause bleeding. This situation is difficult to deal with. It is recommended that the owner first take the cat to the pet hospital for relevant examinations to confirm the size, location and nature of the tumor. If it is a benign tumor, it can be cured through surgeryUse medicine for treatment. If it is a malignant tumor, drug control treatment is recommended.
