Small update: I ended up making a drive down on the 14th to get him some live rats. I was too worried about him possibly going another month without eating, it wouldn't be fair to him. He's eaten two rats since I posted this so he'll definitely be good to go! We're moving in 5 days so he won't have to go without food for very long. Plus, he's due to be going into shed any day now so it might work out perfectly. After we get there, I'm going to work on transitioning him to frozen thawed rats.
Thanks to everybody who responded! (:
