1 year ago I had recently rehomed a young female kitten. She was digging at her ears so I picked up some HARTZ ear mite medicine. I had a 15 pound male house cat already. He is my best buddy. Since I had had her a couple of weeks already I have him some drops as a preventative. Two days later he stopped eating or drinking, couldn’t walk and was crying in pain. I took him to my vet. His temp was 105. As soon as I told him what I had given him he knew he was poisoned. He gave him fluids and some antibiotics but didn’t have much hope. The vet told me to never use HARTZ products under any circumstances. I cried so much the next few days knowing I had done this to him. It took 7 days and $300 in vet billz before he started to get better. HARTZ needs to be put out of business.
