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.
