Hello. My 4 year old cat has known allergies and therefore, is often pawing at her ears. I clean them weekly with Salicylic Acid (as prescribed by our vet). 2 days I noticed that she as a foul odor coming from her ears. Is this a part of her ear allergies or is it an infection? I’d hate to drag her into the vet (very stressful for her) for them just to tell me the odor is a part of the allergy. I also do want to ignore thing if the problem has gotten worse. Thank you!
