What are ear mites?
Ear mites are mites that live in the ears of animals and humans. The most commonly seen species in veterinary medicine is Otodectes cynotis This species, despite its name, is also responsible for 90% of ear mite infections in cats.
In veterinary practice, ear mite infections in dogs and cats may present as a disease that causes intense itching in one or both ears, which in turn triggers scratching at the affected ear. An unusually dark colored ear wax may also be produced. Cats, as well as dogs with erect ears that have control over ear direction, may be seen with one or both ear pinnas held at an odd or flattened angle.
