Some cats seem to develop immunity to mites, so younger cats are more likely to to be afflicted. Cats with suppressed immune systems are likewise at higher risk. If left untreated, they can lead to accompanying secondary bacterial and yeast infections.



What are ear mites? -- Mites are small, crab-like parasites that typically live on the head, and in the ears. In more extreme cases, they can cause a rupture of the ear drum, and may lead to deafness and even seizures. Mites are the most common cause of outer-ear inflammation in cats.

Sensitivity to mite infestations varies, with some cats appearing less bothered by it than others. Younger cats are typically more sensitive than older cats.

Symptoms -- Frequent scratching of the ears and shaking of the head are the most common symptoms. The most obvious sign of ear mites in cats is a build up of black wax that looks like coffee grounds.

As can happen with parasite infestation, secondary bacterial infection is not uncommon. Some cats may experience a loss of hair around the ears, and the waxy build up may cause additional irritation in the ear.

In more severe cases, excessive scratching may cause ulceration at the back of the ear. This may lead to permanent disfigurement.

Treating mites -- To avoid damage to the ear, treatment for ear mites in cats should be done by a veterinarian and begins with cleaning out the ears.

Mineral oil may be used to soften the wax. Flushing out the ears removes a large number of mites and dislodges the wax at the same time.

After the ears are cleaned, an ear mite treatment can be administered. Flea control medication is often used to prevent a recurrence of infestation by any mites that have migrated to some place other than the ear. Over-the-counter remedies will typically take longer to work than the ear mite treatment preparations from your veterinarian.

Ear mites in cats can also be spread to other animals in the house, including people. Physical contact with affected cats, therefore, should be limited. This is a very treatable condition, although treatment may take quite some time in more severe cases, and your veterinarian may administer "off-label" drugs.
