Does anyone know if Frontline Plus will help with ear mites? Im not positive my cat has them, but I am seeing some dark bits of waxy substance in her ears. I just recently went through a very long battle with fleas. My sister brought her cats into my home with fleas, after telling me and swearing up and down they don't have them. Now that that is under control,(and her and her cats are out of my home) I'm now wondering if they might have ear mites from my sisters cats as well.. I just finally put frontline on both my cats three days ago, I was able to afford it finally, phew! I'm guessing it doesn't help with ear mites.. any advice? I can't afford to bring them to the vet for at least another 3 weeks..
