Yes… another one… This sweet little girl that we adopted a few days ago is now fighting for her life due to Hartz Advanced Care Flea and Tick for Cats & Kittens. I followed the instructions to the letter and she became lethargic and eventually fell into tremors. We rushed her to the vet, where she is being cared for. She made it through the night and we hope she’ll make a full recovery. However, if we had not acted so quickly she would have certainly died. It is unacceptable that this product is on the market, as its effect is so unpredictable. We used it on one other cat at the same, and he lost some hair and had skin irritation. I will never buy another Hartz product as long as I live.
