In the past 3 years I have seen several Hartz flea and tick product victims. It is always heart breaking to us when a client brings in their pet, who they lovingly tried to help by ridding them of fleas only to find they have done more harm than good. Most of our Hartz victim kitties make it, but sadly some do not.
My condolences to all of you that have lost your pets. I will spread the word about this product as I have for the past 3 years and perhaps one day the company will get the message and pull this horrid product off the shelves!
