Hi Suzanne, One of my Newbies brought ear mites into the home and so all eight of mine had to be treated. My vet opted to use Revolution (Selamectin) at feline doses. However, he weighed each one separately and administered a dose appropriate to each by putting it into a syringe. It was a bit expensive and time consuming but I know all my babies are safe and the mites are history. He recommended redoing them once more in 3 weeks time. I believe Revolution can be used for fleas as well. Tressie A.
