People worry too much about "schedules". Snakes don't know the schedule, and they don't care about the schedule. Give the snake a few days and feed it again. They can easily eat every three days if you are worried about getting back on schedule. My snakes haven't once been on a schedule. They get fed on different days, at different times, and they all eat just fine. If they were in the wild a rodent wouldn't waltz in front of their face every Monday night a 8, they eat when they get the chance.
