This morning, he was furiously running on his wheel, like always, although this was the first time I'd seen him loop-the-loop consistantly...
I petted him and went to school.
Just got back from school. He's not moving. He was crawled up in his little toilet paper tube. I pulled him out, and he's in my lap now, but he's still barely moving at all--he'll move his head a bit when I pet him, but that's it. He feels a bit cold. Normally he's running all over my arms and shoulders until he gets on the top of my head.
What should I do?
