Ball Python Soaking?

[Bogertophis]

He must be messing with me. He was out and about for a few days. Sleeping in his hides and exploring. I thought all this was over. THEN I fed him last night and he's back in his bowl. All day today.
WHY LOKI!? Why do you stress your mother so?!

They do absorb some water while soaking, and they do need extra hydration both for digesting and shedding, so maybe he just senses that he needs this?

Or maybe he's like the little kid that will only drink thru a straw...have you tried giving him a colorful straw?

On the other hand, maybe he's diabetic? if there IS such a thing??? (I don't see why not...or hyperglycemic?)
