I think this product is truly amazing! With 5 house cats two of which go in and out, we are flea free! I can remember a time when a flea comb and powder were the only weapons available. I was fighting fleas constantly. Now a once a month application and the cats, the house and me stay flea free! Truly amazing and wonderful!

My cat doesn't have fleas so I guess it works.

Works faster and longer than the regular Advantage..fleas seem to become immune to it but not Advantage II. Within 1 day all pets were flea free.

I'm really pleased with the results! I will use again!

In one treatment the fleas are gone!

I rescued a small dog who then, later, I realized had fleas -- and my 6 house cats began to get them. I started using this product and have been happy with the results! I will continue to use it monthly.

Have used for at least 3 years & will continue to use as we have had no problems with fleas & easy to apply.
