Q: What is the best way to clean a cat's ears? There's a lot gunk in my cat's ears and I want to clean it out, but I'm not sure of the best way to approach her.

A: Cleaning your cat's ears, thank goodness, is one of those things that does not usually need to be done frequently. Cats are generally very good about keeping themselves well groomed, and that often includes taking care of their ears. There are times, however, when dirt will accumulate on the inside of the ear, where there is a protective wax covering, just like our ears have. This dirty appearance is usually confined to the upper part of the inside of the ear, and does not affect the ear canal. If this is the case, lightly moisten a cotton ball with hydrogen peroxide, and gently wipe the dirt out. Do this as you pet your cat, and often they will allow you to freely rub the ear with the cotton ball.

If the ears appear very dark and dirty, it may be a sign of ear mites (which cats will pick up from the garden or yard) and this will need veterinary attention. Usually the cat will do quite a lot of scratching and shaking of the ears and head if mites are involved. Special medication will be required to rid the ears of the mites, so if any irritation of the ears is apparent, you should consult your veterinarian.
