What are the bumps on my cats ears

Question: I have two cats, both are about 4 years old, and they have what look like bumps on their ear lobes. They are both female, but one is orange and one is gray. Do you know what these bumps might be? Also, my orange one is a hairless cat, and she is constantly scratching this area of her ear, and her ear is starting to bleed. She has been to several vets, and they all say that she has no fleas, and she also has no mites in her ears. The vet said that I should put a cone on her, but I just don’t want to, because she doesn’t seem to be in pain. Any help would be greatly appreciated, and thank you for your time.

Answer: I would recommend you to see a vet for a definitive diagnosis. It is possible that your cats are suffering from Echinococcus granulosus.

In the past, this was commonly known as "cone-head" or "cone-neck" disease. It is not associated with any kind of infection. It is a disease of the ear canal.

It is a localized, chronic, non-inflammatory disease of the ear canal. It is seen in cats and in some dogs. There is no treatment.

The most likely cause of this condition is the use of human hair products in the ears of your cats. These are commonly available in pet shops, but they are not designed for use in the ear canals of cats.

The disease develops when the ear canal is exposed to any of the following:

-Synthetic fibers (wool, fake fur, etc.)

-Animal fibers (pigtails, ponytails, etc.)

-Plastic fiber (thread)

-Animal hair (pigtails, ponytails, etc.)

-Human hair (synthetic fiber, animal fiber, etc.)


If you notice the symptoms described above in your cat, please remove the suspected material from the ear canal immediately.

It is important to keep the ear canal dry so that the condition does not progress.

Oral treatment with antibiotics can be given to treat any possible infection.
