I stumbled across this website doing some research and thought I would share a horrible story with all of you regarding a hartz product. We had this all gray long haired cat named Holly. Christmas Eve she was doing great. Christmas Day we woke up and she was laying under the Christmas tree dead. Our 4 year old found her. She was at the vet a week before and given a clean bill of health. We put a Hartz flea and tick collar on her the 22nd. It was a very bad Christmas to say the least. How can a company remain in business after killing so many animals?
