Recently i purchased Hartz flea remover for my two kittens. I tried everything in the petstore nearest me to get rid of there fleas. I decided to go to another petstore and ask one of the employees to recommend something. He chose Hartz and said “With a name like Hartz, who wouldnt trust it?”. That sold me. Taking home my box of Hartz I felt relieved my babies would have some relief from thier constant scratching. I bathed them and put on the drops as recommended. I woke up the next morning to let my 6 week old puppies (as you can see i’m a pet lover and future vet tech) out of thier cage, when i saw the gruesome sight. Layin by the water bowl was Tyga, my 3 month old grey tabby, stiff and with blood coming out of his mouth. About a foot away movement caught my eye. It was Frankie, my 9 month old larger grey tabby, having a seizure. I quickly grbbed my cats, left the puppies with my boyfriend, and rushed to the vet. All i kept thinking was I bet it was that flea stuff, that darn cheap flea stuff, and man was i right. My vet confirmed it. Hartz killed one of my babies and made the other have seizures. There was no way to save him, the vet said. Just great, Hartz killed BOTH of my babies. Dont let this happen to you.
