I just went to check on her, and she was cruising around the tub... I noticed a bunch of pee, so I lifted the hide & found a GIANT poop and urates too! Guess she's feeling comfortable and ready to eat, LOL.

I also moved the probe right on the UTH, and it's now reading over 100 degrees. But the ambient temperature is still a little under 80, so could that be possible? To clarify, you said to stick it under the newspaper - directly on the plastic?
