I know it sucks, but there's not much you can do beyond making sure husbandry is in check! As long as he's not losing a tremendous amount of weight, he'll be fine. They can go months (even a year!) without food and hardly be affected. If I suspect an extended fast, I'll only try feeding once every 2 or 3 weeks to save on wasted rats (although I do live near a small body of water, so I just throw any uneaten rats out there for the lucky water snake who happens to come upon a free meal...the frozen rats don't last long out there)!![]()
