I use a snake hook to open the tub, because I usually get bit while opening the tub. If the snake dives out (which is quite often this time of year), I gently move them back into the tub with the hook, then drop the rat in at the same time and close the tub. I have a rat in one hand and the hook in the other when feeding. I've always looked at this type of feeding response as a good thing! Love it when I have to duck and weave to feed the snakes. It means they are ready!
