Last summer my husband got laid off from work and to save money we used Hartz on our baby. She almost died and it was the worst few days of my life. She recovered and we learned a valuable lesson. I took a job at Walmart until my husband could go back to work and I would tell every single person that came through my line with any Hartz product that the stuff was poison and would kill their cats. My thought was that I did not care if Walmart fired me if I could save at least one life. One night my boss overheard me and I was coached several times for telling customers to not buy a product. I kept doing it and was honestly on the verge of being fired when my husband finally got called back to work. The point is that something needs to be done, Hartz knows this stuff is garbage, the stores selling it knows it is garbage and because it makes money NO ONE cares. All Hartz will do is send you a check for 8 dollars and apologize and Walmart will nearly fire a good employee for trying to save an animals life.
