Review title: No longer works
Product review: I have used Frontline for years on my cats and it worked great. I could smell the product as I applied it to each cat, and the flees stayed away. Now i apply the Frontline to the cats and nothing happens. My cats are still scratching like crazy as if I had applied nothing on them but water. I can no longer smell the medicine as I apply it to the cats. Frontline must have changed its formula and it was not for the best.
