Ear Mite Treatment

What is the best treatment to use for esrmites without going to a vet? Thank you!

Are you certain it is ear mites, usually the ears are itchy to the cat and there is a coffee ground like substance in the ears. I've used just a single drop in both cat ears with good success with this brand. These drops are strong. I only recommend this brand, http://www.drsfostersmith.com/product/prod_display.cfm?pcatid=25251

You may or may not need something stronger from a Vet. I am by no means giving medical advice, only recommending a product I've used.

Yes she lets me touch her and I see black gook in it. I cleaned it out and put some food grade DE but she is still scratching them.
Thank you for the link! I can't seem to find it anywhere online!
