Frontline or Advantage?

I just found a flea on one of my cats which mean all ten have them.
Which do you all use?? I was looking at frontline plus. Does one of the tubes really protect for three months??(All of my cats are inside all the time)

You really want to switch out, use advantage one time, then at the next application use frontline- that way the fleas don't build up a resistance to the one brand-

Good idea. Thanx!

You may want to look into Revolution too. Weve found it to be a bit better and it has a dewormer in it.

frontline doesn't work on my cat for some reason. unfortunately for me, it is much more widely used now than advantage is. (advantage has always worked on her). i finally found a place that carries advantage, but i had to buy a 4-pack of it.

with advantage, you will probably need to take kitty to the vet to have him/her weighed, since there are 2 different weight specs for it. under 9 lbs and over 9 lbs.
