My cat has been to the Vet for ear cleanings and Tresaderm drops for the treatments of eremites. He is also on Advantage. They never seem to totally go away. He is an indoor cat and has a cat door to the screened in 2nd floor balcony. He never goes outside except the balcony. He is clean and very well taken care of. I need advice on what else I can try or what to ask before going to the Vet for the third time for this problem in the last eight months.
