Our cat, Eminem, got really sick after we used the Hartz flea and tick spray for cats. For two days he couldn’t eat or drink anything, by the second day he couldn’t even stand up without falling over.He cried anytime anyone touched him or picked him up.The vet had too put him on antibiotics, morphine and two IV’s for the dehydration caused.I called the 1-800 number on the back of the HARTZ product- they said it sounded like I overdosed him. I only used half of the recommended dose for his size. Its time for Hartz to admit their product is not safe. do they use this on their own animals?
