Do not feed a snake another food item if more than half an hour has passed since they ate the first one as this can mess with their digestion. If Mia is a healthy adult BP, it won't do her any harm to wait until the next feeding day. Snakes often continue to act hungry after eating because they go into a sort of "feeding mode" mindset that can last up to 48 hrs, plus the lingering smell of rodent in their enclosures seems to encourage this.
