It looked digested, the mouse was the same as always... his cool hide is about 75 degrees, his warm one is about 87. He's been in his cool hide for a week, then last night was on the warm side... Maybe needed the heat to help him get rid of that huge turd?
I'll step up his food size; should I keep him on a once-a-week diet, or make it more frequent?
You should raise your temperatures a little bit, it may be a little too cold, which might be why it doesn't poop so often. I would raise your hot side to about 93- 90 degrees, and your cold side to 80- 85 degrees.
