Hi Mimi,

It was me who was complaining about Advantage.

BUUUTTTT this is what we know around here. Lot of people in our area have been using Advantage and the fleas have developed an immunity to them. Several of the vets in the area were telling us that many of their clients were saying that Advantage was not working. Fleas on our cats have been resistant to Advantage since about two years ago.

Frontline seems to work and lot of people in our area have switched to them. We have switched to Revolution as it takes care of several other parasites and bugs. mites and ticks?? Revolution isn't as readily available.

What you need to find out is what majority of the people in your area are using and call several vets in area to find out if any have heard of "advantage doesn't work anymore" or "frontline isn't working anymore" . If neither is working then you need to go to Revolution. Its available only through a vet.

hope this helps.
