Came to this site through a thread. I am extremely upset reading all this. Quite a few years ago I worked at a pet store, and our owner NEVER carried Hartz products, I know this is about the dips, powders and collars, but the quality of the food and treats are also deplorable. To test seed grow some, I tried this and Hartz didn’t grow, nothing. My son made a mistake and bought a hamster treat that made his little friend VERY sick. Almost killed her. There have been numerous articals and shows about this and if the people selling and retailing knew the facts they could do what I did and still do, Tell people it may cost a little more but you do it for yourselves and your family and aren’t pets family?
