Why is my cat constantly scratching her ears? Is it mites?
Constant scratching is a potential symptom of a parasitic infestation of “ear mites.” Ear mites are a common problem among cats, especially those that go outdoors. They are not visible to the naked eye, but your veterinarian can take a swab of the ear and examine it under a microscope to diagnose an infestation. If that is the case, there are a few medications that could be used to treat this condition. It will usually clear up in about 4 weeks. If there are no mites present, the microscopic examination can also show if there is another problem such as bacteria or yeast. If that is the case, your veterinarian will prescribe the appropriate treatment.
