"I have two indoor cats that I had been using Frontline on but still noticed fleas on them, so I called the vet for advice. They suggested that I switch to Advantage because fleas were becoming immune to the chemicals in Frontline. The fleas were so bad that they were taking over my house and I was starting to get chewed up too! So I used Advantage, and a day later, I have not seen any fleas on the cats and they don't seem to be scratching or biting anymore. We used foggers to kill the fleas in the house. I am extremely impressed by Advantage. I would definitely recommend! This product is AMAZING!"
