From the moment you apply it to your pet's skin, Revolution moves into the bloodstream, where it prevents heartworm. Then it moves into your pet's intestines, where it treats parasites like roundworm and hookworm in cats.

From the bloodstream, Revolution returns to the skin and hair folicles, to protect your pet from parasites like fleas, sarcoptic mange and ear mites. And just one dose does all this for a whole month.
