Only recently have I learned that using Hartz flea control on cats caused numerous deaths and other problems. I used Hartz maybe about a year ago on my cat. Now I'm wondering...sometimes her back will twitch every now and then. I never really thought to ask the vet about it since it didn't seem like a big deal and doesn't happen all the time. BUT could it be something related to the Hartz flea meds that I put on her?! I would NEVER have used it if I thought it there were any problems...I don't even know why it is sold! :shock: :x
Any thoughts?
