No more fleas. Happy cats.

I have used the other name brand for years. It is now starting to fail. It didn't even last for three weeks. So I decided to try Advantage II. I use this on all three of my cats as we recently somehow got a flea infestation. It worked wonderful. My cats have all stop scratching, and I can't find a single flea on them. I have found many dead fleas around their water dishes, but no life please. It works great and I definitely recommend this product.

Best price anywhere. As long as I use this as directed for my 2 cats, they never have fleas. They also do not experience any negative side effects from it. Have been using it for 7 years. Thank you Walmart for carrying this. Not everyone does. I feel this product is safe for my beloved cats.

Advantage II has always been my go to for flea control on my cats.. it works great… when you’re buying from Walmart always make sure it’s shipped directly by Walmart not by a third-party.. that way you can make sure you are getting the genuine product . Walmart is an approved vendor for advantage II
