I've had my local Banfield vet check my cat because of dark spots in the ear and local hair loss on the same ear. They did an ear swab that showed nothing wrong, even though there is dark icky build up in his ear, there is no smell, foreign bodies or pus.
1 week later my cat's ear started feeling dry and slightly scabby, so I took him back to have them double check the ear. They did the second ear swab 10 days after the first. They say the results are negative, nothing in the ear. No mites, fungus or bacteria, and the hair loss is normal for senior cats, my cat is almost 15 years. The affected area seems to be getting more dry and scabby, but my cat doesn't seem to be bothered by it, no scratching, no head shaking, no redness, swelling or bumps that are obvious to me.
Should I take my cat to another vet for a second opinion?
