Ear mites are just plain gross, especially when it is your cat who has them. These little critters can cause some significant pain if your cat gets infected. The best way to prevent an infection is not being around other cats and keeping your cat indoors. If your cat is shaking its head, scratching its ears or has ear canals filled with black debris please let us evaluate those ears for ear mites. Luckily the treatments are very effective.
There are several types of ear mites that can live in cats’ ears, but the most common are Otodectes cynotis, tiny, eight-legged parasites that feed on the wax and oils in a cat’s ear canal. An individual mite has an approximately three-week life cycle, and is barely detectable by the naked eye. Causing irritation and inflammation, ear mites can infect the external and internal canal, and lead to more serious skin or ear infections if left untreated. Infection usually produces a characteristic dark discharge-and in the most severe cases, a cat’s ear canal can become entirely obstructed by this coffee ground-like debris.
What Causes Ear Mites in Cats?
Highly contagious, ear mites are often passed from pet to pet in casual contact at home or outside. Though they can infect both cats and dogs, ear mites are much more common in cats, and are responsible for more than 50 percent of all feline ear infections. Humans are generally immune to ear mites.
What Are the General Symptoms of Ear Mites in Cats?
- Excessive scratching and rubbing of ears
- Head shaking
- Hair loss and dermatitis
- Black or brown waxy secretion
- Strong odor
- Inflammation of the ear
- Obstruction of ear canal with coffee ground-like debris
- Scratches or scabs near ear
What Are Some Complications of Ear Mites in Cats?
In addition to the development of skin infections, ear mites can cause blood vessels inside a cat’s ear to rupture from intense scratching and head shaking. This is known as an aural hematoma, and often requires surgery to correct.
