As long as they have water and a dish of mealworms, I would say up to a week. Of course if you live in a cold place and are worried about the power going out, that's something you would want to take into account.
Yeah I think we went through all this in another thread.
They can go w/o food for a days but not water.
The water needs to at least be checked every day because they can knock it over, bath in it, poop in it, etc.
Also, the humid hide needs to be checked every day as well (unless they JUST shed)! :main_yes:
