I had read a couple weeks ago (I don't remember where at, but it was online) that lateral wrinkles on the python's skin can equate to lack of food or water. Of course, this just gave me something new to obsessively worry about, and while holding Mr. Bojangles today, I noticed such wrinkles. Of course, I would think that they would be normal where the snake bends and twists, and the skin folds to compensate for the shape-change, but I thought I'd ask to make sure.
