Ear Infection?

I would change the bedding, remove corn, wheat, peanuts and sunflower seeds form the diet, and be sure that the environment is not too noisy, too bright, and especially, too dusty. This includes dust from excess clutter such as clothing or books and papers, carpeting, other pets and any other source. I used to have problems with icky ears in my mousery, and I tried everything I mentioned here, plus the Benadryl, antibiotics, cortisone ointment, and while I did get about half of the meeces through it well enough, I suspect it was just that those meeces were able to fight it off better.
