My husband applied Hartz Ultra Flea and Tick drops for cats > 5lbs on our 8yo Blue Point Himalayan Cat Molly Oct 1, unaware of the toxic and possible lethal effects. He applied the product correctly Oct 1 and noticed Molly was chasing things but did not notice anything else unusual. The next morning he left our cat to go out of town. He felt the cat was ok but noticed the cat did not eat, drink, or use the litter box the entire evening/morning before he left. We returned 48 hrs later to a cat that could not walk, eyes twitching rapidly, mouth foaming, and 14 areas of bilious vomit throughout our house. The litter box, food and water left out for the cat was not touched. I immediately took the cat to the emergency vet explaining the situation. They repeatedly told me how toxic Hartz Flea and Tick products are for the cat as well as my 4 yo child!!! My cat was kept overnight and given IV fluids as well as IV Meds to control the vomiting. His dx was pyrethroid toxicity (HARTZ product). It is now OCT 17 and several return vet visits, overnight stays, multiple medications for continuous vomiting, drooling, 2.5 lb weight loss in my 12 lb beautiful cat, lethargy, food aversion, we have been referred to a vet specialists 1.5 hrs away. My cat now has a feeding tube and is fed 4-6 times a day to assist him in regaining his health. She meows for food and stands around the kitchen but cannot make herself put the food in her mouth. THIS IS HORRIBLE TO WATCH. PLEASE SHARE WITH YOUR FRIENDS BEFORE THEY BUY THIS PRODUCT. WE DID NOT KNOW THE DANGERS AND PLAN ON SPREADING THE NEWS TO THE LOCAL NEWS, PETCO WHERE WE PURCHASED IT,ETC. We did contact HARTZ and they said there is no way the cat should still be effected by their product this far out. They said they did not know their product caused animal harm but then said most of the animals effected are treated at a vet for 48-72 hrs after application. When asked about this website they would not comment. HARTZ DOES NOT CARE! THEY WERE NOT WILLING TO HELP ME OUT AT ALL-THEY ONLY WANTED TO PUT BLAME ON US! I am ashamed to say my vet bill is $3200 but I cannot put a price on my cat’s life. He has never been ill until this product was applied.
