Revolution is for worms as well.
This is from their first paragraph on the site:
We the cats of America deserve freedom from the oppression of our worst enemies: fleas, heartworm, ear mites, hookworm (Anycylostoma tubaeforme) and roundworm (Toxocara cati ). Complete parasite protection begins and ends with Revolution® (selamectin).




My mom and dad use Frontline Plus for all of their cats except one, Lucey, because she get a huge bald spot from it. They put Revolution on Lucey and she does not get an allergic reaction from it at all. It doesn't kill ticks, so she does need a separate topical for that.
