awww! now you feel like a meanie huh? Have they had Revolution before and have they had any reaction?? Mine had Advantage but thankfully they put it on at the vet - so *I* was not the bad guy

I asked because I have heard someone here say that Revolution made their cats act weird and one had a skin reaction. I guess any of the meds can do this, though - different systems on different cats. Mine did not even seem to notice the flea treatment at all.
