This scabicide is VERY POISONOUS to cats. Its in fly & surface spray, flea bbombs & lice treatment. Just put kitty outside if your going to use it in excess for at least a few days. Cats can't spread scabies for even a few hours as they sence if its on them except& lick it off. When you are treating yourself don't let cats rub your legs nor pat them. Your stress also rubs off onto your cat & cleaning & moving stuff around really confuses them. Im sayin this as you don't need a vet bill on top of everything else. Thankyou for reading.
