I don't know where you've been getting your information, but snakes can go months on end with no food, and most do during the breeding season. Even when you bring them out of brumation, they may go another couple of months without any food at all. As long as your snakes are healthy sized when you put them down, they will be fine. My kings and milks are brumating right now, and they will be down for 2.5 months with no food.
