I just received this e-mail from Darah. I have never used Hartz flea collars on our animals. If anyone has any information, please contact me or Darah.

Message: I need to know if there are any known problems with the Hartz Flea Collars.
Within 48 hours of putting one on my cat, she lost all the hair around her neck and
now has a raw, weeping wound. I know the flea drops by Hartz are a problem, but I
think there may be another problem with the collars. Please feel free to email at
