Hey everyone...I've gone through the posts trying to see if this subject has come up. I haven't seen it so forgive me if I've just missed it. I was just wondering if anyone has used a new flea control product called Comfortis? It comes in pill form. So no greasy spot left behind. If anyone has used it I would love to hear what you thought about it. I know its a bit more then Advantage or Frontline.....Thanks Lisa
