Almost every time I've rescued a kitten, its had ringworm. Its insane to think that this is reason to kill . Also, every time a kitten has ringworm, I get it, almost always on my leg. Having been through this I speak from experience....Lamisil is the best OTC ringworm med (at least for people, check with your vet before using on a kitten). By the fourth or fifth day, I have to use a Sharpie on my leg, so I'll know where to keep putting the medicine because the pink and the itch disappear so quickly....Hope you and the kitties get better...
