So for the past three weeks, my corn (who is normally a fantastic eater) has been refusing food. He takes the f/t mouse and drags it around his enclosure for a long time, but doesn't eat! It's almost like a kid pushing his veggies around on his plate cause he won't eat them... Any suggestions on how to get him to eat? It's the same mice that he's been eating for months now, and I'm thawing it the same, etc....
