I take care of a small colony of feral cats in my backyard. All of them have been TNR'd and are in good health.
However, one of them has a bad case of ear mites. He will not let me get within 3 feet of him, so topical treatments are out of the question.
Are there any oral treatments for ear mites? I know that ivermectin kills ear mites when applied topically and injected. But would this work if given orally (through a medication such as Heartgard)?
This poor cat has been scratching his ear to the point where it is bleeding. So I'm desperately looking for something to help him. Catching him and taking him to the vet isn't an option either. He is nearly impossible to catch.
