Revolution for Cats

As is the case with dogs, veterinarians and pet-care experts overwhelmingly prefer topical flea-control medications for cats, and no product is cited more often than Revolution for Cats. This ointment is applied once a month to the nape of the cat's neck, and controls fleas, heartworm, hookworm, roundworm and ear mites for four weeks -- regardless of baths, shampoos or thunderstorms. Revolution for Cats is slightly preferred over another topical medication, Advantage, because of its effectiveness against parasites other than fleas. Some experts, however, say internal medications such as Program Once-a-Month Oral Suspension (*Est. $45 for six-pack) are more effective at controlling fleas; only your veterinarian will know for sure.

The two most convincing recommendations of Revolution for Cats come from veterinary sources: a veterinary assistant's post on Helium.com, on which 14 other writers weigh in on the best flea control products, and DrLarryPetVet.com, where veterinarian Larry Cohen points out that Revolution for Cats is effective on a wide number of parasites. About.com cats guide Franny Syufy also mentions Revolution, but it's not clear if she's tried it.
