Advantage II Flea Treatment for Cats and Kittens prevents, treats, and kills fleas. Advantage gives fast relief to your cat by killing 99% of all adult fleas within 12 hours of application with its powerful main ingredient, imidacloprid. One application lasts one month. Advantage II steps up the superior flea control of Advantage by adding the insect growth regulator pyriproxyfen, preventing flea larvae from growing into adulthood and reproducing, thus attacking the whole life cycle. This treatment is waterproof, so you can rest assured your cat will be protected in any situation. Advantage II is only for cats and kittens eight weeks of age or older.

4 out of 5 eggsMuch more effective than Frontline

Pros: Much cheaper (about half) on-line than through a vet.
It's pungent but it does not seem to bother the cats at all.
Extremely effective for flea treatment.

Cons: Doesn't seem to last a full month as advertised.
Application is a bit difficult for long-haired cats (I have 3). It would be nice if the nozzle were a bit longer to get it down past all the fluff.

Other Thoughts: Tried Frontline and for a while it worked great but then started to not work all that well and then not at all. According to some on-line research, fleas have adapted to and become immune to the chems in Frontline in some parts of the U.S. (I'm in San Antonio, TX).
Also, be careful to use the proper dosage. I once used the large cat dosage on my big boy cat and he had a very worrisome and adverse reaction to it (panting, vocal, and just running around like nuts). I had to give him a bath in the end which was no fun at all but that solved the problem. If in doubt, use this 5-9 pound dosage.
