I've always used OTC stuff (not Hartz, though!) and have had success. So long as you can keep the cats worm free, then the dogs stay worm free (if you have pups who like to dine on the litter box buffet, anyway...)

HOLD IT!! We're talking about two entirely different kinds of parasites.

Ringworm is an internal fungus that shoes up in a round, raised red patch. The area will lose fur. It is HIGHLY contagious. You'll need topical creme and an antibiotic. Where sterile gloves when applying the ointment. Keep any other animals separated.

Roundworms, the most common in kittens, is an intestinal parasite and is treated by Pyrantal. One or two doses should do it.
