Today I buried My 6 year old cat Murphy.Murphy was such a fun loving cat, extremely healthy cat until I used Hartz flea and tick drops. Within a short amount of time Murphy got a far away look in her eyes, quit eating and couldn’t walk without weaving. Before I got her to the vet she couldnt move. She lived through the night but died the next day. I wish I had known about this before I bought that product. Is the few dollars that the Hartz company made worth the life of my sweet cat? My eyes hurt so much from crying and I am so angry.
