Ear Infections in Cats: Causes, Treatment, and Prevention
Cats don't often get ear infections, but when they do, the cause can be complex.
If your vet has ruled out mites -- the culprit in about half of all feline ear infections -- she'll have to do some sleuthing to figure out what's causing your cat's outer or middle ear infection. It could be allergies, or an underlying illness like diabetes, tumors, a damaged eardrum, or feline leukemia virus.
Diagnosing the condition may require sedation or X-rays, but treating ear infections usually isn't complicated. Antibiotics, antiparasitics, and corticosteroids are the most common treatments.
What's essential is that you get your cat in for treatment as soon as you notice signs of ear discomfort. Ear infections can become chronic and lead to deafness and facial paralysis.
What Causes Ear Infections in Cats?
Generally, unless your cat has picked up mites from another animal, ear infections are a secondary condition. That means they are actually the result of some other underlying medical problem.
Here are some of the contributing causes and perpetuating factors for external ear infections, called otitis externa, and middle ear infections, called otitis media:
Infections of the middle ear are usually the result of an infection that has spread there from the outer ear canal. Tumors, a ruptured ear drum, or improper ear cleaning can also lead to middle-ear infections in cats.
