I've seen a couple of threads now where people either advise trying to get a snake onto rat pups or fuzzies rather than feeding mice, or some variant of that conversation. Is there any reason to do other than size for snakes where a mouse isn't enough? I am sure with a finicky eater it's easier to get one big meal in them rather than two, but is there any nutritional reason to feed a rat as opposed to a couple of mice? It could be an availability thing too, as it seems to come up in a lot of the f/t conversations.
