Yes. Snakes will eat F/T when its just left in their enclosure over night. But depending on the snake, it might not eat still either.
What's your husbandry and set up like? If a youngster doesn't eat, 90% of the time its due to environmental factors.
And until your snake eats at least 3 consecutive times, do not handle your snake. You want to keep the stress down to a minimum and maximize its chances to start eating.
