My cat is approximately 12 years old and has always had dark brown stuff in her one ear. I have had vets say it is mites and some say no. No one has ever told me what it is. It seems as if her ear hurts alot and is very red and looks hot. What should I do? She had creme that had been put into her ear once and the vets cannot figure out which one it was. Could it been panethol?
Ask your vet to culture the material in the ear and check under the microscope for mites. Revolution kills mites so you may want to try it. vetcare
