HARTZ almost killed my cat! We thought my cat had flees so we bought a HARTZ product and put it on my cat. She was meowing and running around the house. Then we looked at the reviews of the product and their where reviews that sounded like the same thing that was happening to my cat! So we immediately washed it off. So if you come across a HARTZ product please do not buy it! And please do your research on whatever you put on your pet!
