Much to my horror, I just read your article on Hartz Flea & Tick Control. How I wish I had been made aware of this poision BEFORE I put it on my kitties last night! This a.m., I woke up to a kitty that was shivering, vomiting & convulsing. He could hardly stand and could not walk, because he was so disoriented. We immediately called the poision control number found on the pack of the Hartz package but guess what?? THEY ARE CLOSED ON THE WEEKENDS! We then rushed the kitty to the vet, where we found out that I HAD POISIONED MY OWN KITTY. A few hours later, and several dollars later, our kitty is doing somewhat better. We were told to watch him (& the other kitty as well) to make sure the symptoms do not return….if so, then we will have to spend more money at the emergency room to prevent permanent neurological dammage. Can you please tell us where to turn or offer some advice? I should hope there is something we can do to prevent this from happening again! Thank you for your time & Best of luck!
