Signs of Ear Mites in Cats

Otodectes cynotis is the primary type of ear mite that affects cats. It is an oval parasite that has eight legs and lives on the surface of the ear canal. This can result in a number of problems that range from an allergic reactions to infections and even potential hearing loss. According to the SPCA, ear mites are the cause of 50 percent of feline ear infections. If you suspect that your cat has ear mites, there are specific signs to look out for.

  1. Scratching

    • Persistent scratching of the ears as a result of irritation is one of the most common indications that your cat has an ear mite infestation. This may occur in varying degrees, with mild scratching in some pets, to vigorous scratching if the cat has developed an allergy to the mites or if the presence of ear mites has become severe. An aural hematoma, which is a blood blister may develop on the ear as a result of excessive scratching.

    Signs of Discharge

    • If you suspect that your cat has ear mites, look inside of its ear. If there is a problem, there may be a dark brown or a red-brown waxy discharge present. This discharge looks similar in appearance to coffee grounds and is a combination of blood and ear wax. This buildup may become excessive to the point that it blocks the ear canal. In addition, it may also have a foul or unpleasant odor that is associated with it.

    Shaking of the Head

    • If your cat shakes its head routinely for no apparent reason, it may be an indication that there is a possible ear mite problem. This generally occurs in more advanced cases of infestation. Excessive or hard head shaking may make the cat dizzy or it may also cause the blood vessels to rupture inside of the cat's ears if the shaking is intense.

    Scabs or Lesions on the Ears

    • Cats infected with ear mites may also have lesions, crusted rashes or hair loss on or around their ears. This is due to excessive scratching and runs the risk of infection. There may also be signs of inflammation, which is also a potential symptom of ear mites. Self-inflicted wounds due to extreme scratching may also appear on the cat's neck or head.
