Cat ear

Ear canal tumors in cats are masses that occur in the ear canal and can begin in the skin, sweat gland, and muscle tissues of the ear.

Otitis media and interna refer to inflammation of the middle and inner ear. These terms are often used as synonyms for middle and inner ear infections.

Otitis externa is inflammation of the external part of the ear canal. In cats, otitis externa is most commonly caused by ear infections and the terms are often used synonymously.  

Polyps are benign, non cancerous masses which can grow in multiple locations in cats. A common location of polyps in cats is the eustachian tube, which connects the middle ear with the nasal cavity.

Ear mites are a common parasite found in the ear canal of cats. These microscopic creatures live on the surface of the skin, feeding on skin oil and ear wax.
