Which did you use, Advantage or Frontline? I ask because you SAID you used Frontline but then talked about sending the pictures to "advantage" (Bayer manufactures Advantage).
I use Advantage and have not had any cats lose hair from it, although they certainly hate having the flea medication put on and they make a face of distaste (well,most of them do, but not all).
