about the bag killing method. i have heard and seen that it is not the most efficient instant killing whack method. as you guys have said sometimes it doesn't die the first or second time so essentially it is just getting banged around really hard for a bit before it dies and that doesn't really sound that humane. i have come to approve of whacking it by taking it by the tail (nobag) and wacking it on a wooden step or table ledge etc., right at the head so it's neck breaks instantly and dies instantly. it's a little more difficult because it takes precision whacking and also no bag brings you a little more intimately into the the killing but i think it is more efficient and better for the rat.
