As with the other stories stated, I, too, was unaware of the Hartz flea and tick horror. This evening I unassumingly applied Hartz Flea and tick prevntion drops to my cat, Cleo. Within seconds she started vomitting and foaming at the mouth. We immediately called our vet and were advised to wash her off w/ Dawn dish detergent. She seems better now but we’ll have to keep a watchful eye on her. We feel lucky to have had such a minor reaction compared to other stories. Words cannot describe how infuriated I am at Hartz and I will find out any other products that they make so I can boycott them!
