I had no idea that hartz flea drops where so dangerous and toxic to cats ! I would have never used it on my sweet 2 year old blind cat . I just left the vet and not sure if she is going to make it but I am so damn mad that Hartz still sells this crab that is killing cats . I think something needs to be done to prevent this from hapening to ohter cats and kittens not to mention my $1200 vet bill ! Would love some advice !!
