Hey, that's GREAT that he ate a few crix !! Good for you and Norbert ! He even looks pretty good in that picture . Now just be sure....that those crix aren't too big !! Very important especially since he's not been well ! If in doubt, you can just kill them and remove the head, then feed him half a cricket at a time. You can't afford to have him get impacted on top of his recent problems. A little baby food squash with honey can help him poo if need be, but just see how he does. Oh, one more thing, he can easily get through the screen at the top, try to lower the log by about 4 inches. The recommended distance is fine at 8-10" .
