I wont get into all the details. but happy to see Medusa using both her hides in a normal way. I put on a warmer light this a.m.- on her warm side, because it was very chilly in the house this a.m. But apparently she was just fine, because later I went back to check the temps and she had moved to the cool side.
This is the first time she has acted like a "normal snake", using both hides

I was so excited, I exclaimed "Good job Medusa!"- thats the best part, the kids LOVE when I talk to her like she's a little kitten. LOL
