i usually give mine a wack in the head with the fat end of a screw driver, ive been been twice from reaching my hand down the the box the rats come in. this is kinda graphic and cruel but there usually still twitching after nad i just throw it right in the take and fluffy finishes it off. a few times when she dosnt go for it right off the bat the rat just stops kicking, then i know its gonna be a long night. i would love to get her to f/t because im payin about 6.50 for a small rat right now and shes eating 2 a week.
