Ear Mites Infestation with ear mites (Otodectes cynotis), is common in cats. The mites live on the skin surface; they are non-burrowing but irritate the ear, filling the canal with wax, blood, and mite exudate. Some cats develop intense irritation with the presence of only a few mites. The immune system appears to limit infestations in most mature cats. Infested cats will often shake the head and twitch or rub the ears. Brownish-black debris is usually evident in the external canals. The presence of a brownish ear discharge and evidence of scratching at the ears is highly suggestive of ear mites. Under ear examination the white mites are often seen moving. Although some cats have an extreme response to the presence of ear mites, others are relatively asymptomatic. Topical ear drops can be used for treatment of ear mites and selamectin can be applied to the skin. The prognosis is good with appropriate treatment. |
