It works.
Plain and simple, it works and it's easy to use. You just pop the top, and squeeze the tiny tube onto the back of their necks. Of course our cats hate it, but they need to be humbled a little bit every now and then. They start trying to rub it off, and that actually makes it spread around into their fur. Ha Ha! You have to be careful, though. Because if your cats are like ours, they will wait a little while after the application. The sneaky little jerks will wait until they think you have forgotten about the horrible, horrible thing you just did to them. And then they will come up next to you and put the back of their necks ever so lovingly into the cup of your hand to force you to pet them. You think they're being sweet, adorable cats -- purring is actually involved -- but then suddenly you realize you've been had, and the cats are making you rub the stuff off their fur.

Easy solution to a really gross problems
I feed several feral cats and bring the fleas inside to my cats. With one treatment, no more scratching cats and no more fleas on my socks.

Keeps the fleas away
We have an indoor cat that occasionally gets fleas. This product has been very effective, but pricey.

Advantage Works for fleas in my area
I live in area with sandy soil and fleas. I have tried other flea treatments for my cat (Frontline Plus and Hartz, for example) and still had a problem with fleas. Sometimes the Frontline worked, sometimes it didn't. I mentioned this to my neighbor and she said she had the same problem until she tried Advantage. I decided to give it a try and it worked. No more fleas!

No more fleas
Last year i tried using frontline on my cats, but one of them got sick, so this year i went back to advantage. I started them a little late, in July...so the fleas were already everywhere. It's been a week since their second application and i can already feel the relief. I would recommend advantage, it works great, just remember to start cats on it before flea season.
