I am writing about Hartz flea and tick topical solution for cats. I put this on my cat Tazi Monday night. She started acting a little funny. I thought is was just because she didn’t like the way it smelled. The next morning she could not hardly walk and had horrible tremors. I rushed her to the vet where they treated her with iv fluids,injections and muscle relaxers. She got a bit better until tonight. She is losing her hair and is restless,twitchy and itchy. I now have to take her back to the vet. This product is dispicable!!! SHAME ON YOU HARTZ!!!
