And that's ^ ^ ^ what I do also- keep a little chart for each snake- 3x5" cards work fine or however you want to do it, but it sure beats memory for really knowing how much (or how little) a snake has been eating. Especially when you have a bunch of snakes, as I always have. I finally stopped noting sheds, but anything else that's unusual gets noted too- not just meals. This really helps a lot if you ever need to take your snake to a vet- they get a lot more information this way.
