Ear mites are microscopic parasites that infest the ears of dogs, and more commonly, cats.
The ear mite most frequently seen in companion animals is Otodectes cynotis. An infestation is called otodectic mange, and can cause your cat or dog a great deal of discomfort between the itching and irritation.
Kittens and outdoor cats are more commonly affected with ear mites than dogs or felines that live indoors. The infestation is spread when an animal with ear mites comes in direct contact with another cat or dog.
These parasites are most often found in the ear, however, they can also infest other areas of your pet's body.
