Any vet should be able to sort this problem out in ten seconds flat - if they can't, you need to find another vet pronto!Get some Revolution, because it treats ear mites and fleas. Get it on the SKIN of the cats, not the fur. You also need to pick up some treatment for your house because until you sort out the fleas living in the environment, you will always see fleas.Do NOT wash your cats - flea shampoos don't work, and they will inactivate the Frontline or whatever spot-on you use. And don't put flea collars on them either, these don't work and are sometimes dangerous!!Seriously, if your vets can't sort out a basic problem like fleas and earmites, go to another!Chalice
