I was using Frontline on my cats, and about 5 years ago it just stopped working. The vet said that quite a few patients had reported that, and that the fleas in this area had apparently become resistant. I have been using Advantix II on the dog, (Advantage on the cat) since then with no problems. I much prefer to use natural methods when possible, but Benjamin becomes extremely itchy for days if he gets even one flea bite, so I have to use something that works. It would probably be best to ask your vet if one or the other of these products is more effective locally.
