My 3 yr old cat won't stop scratching his head between his eye and ear. I've taken him to 2 differnet vets. He's had a biopsy which came back normal. No ear mites, allergies, fleas or skin problems present. Has anyone else had this problem ? I'm running out of ideas - although it doesn't seem to bother him I just don't want to see my fur baby scratching his lil head any longer .. it's been too long trying to resolve this. Looking for any thoughts or similar experiences. Thanks .
