My cat has Acne on her ears!!!
My cat Ms. Thang has acne on her ears!!! It can get really bad. At first I thought she had an infection or flea bites. I took her to the vet and he did a test. It cost me $50 to find out she had a pimple!!! She is fixed. Don't know the cause.
She gets the pimple out breaks on her ears maybe twice a year. Sometimes her whole ear isn nothing but little bumps. I don't put anything on them because she would lick it off and make a mess. What I do do is simply rub them or put alchohol on them if they start bleeding. The more I rub them the sooner they scab up and fall off.
The pimples do go away within a month and don't reappear for awhile. It may be about the time for her heat cycle.
I thought that can food can cause pimples. I don't think it could be the dishes.
