Look, I get that it looks like his back must be impossibly cramped, but he's the one who fell asleep that way. And if he looks that comfortable getting in some much-needed rest, should you really be questioning it? Just let the sleeping dragon lie, and if he wakes up complaining about his back then you can point out how very twisted about he was sleeping. Otherwise, shush and let him sleep. Besides, who could want to wake up such a happy snout?

This commission was drawn by  TheOwlette! Who has done a very nice job here of rendering some classic impossible feline-esque flexibility and even put such a blissfully happy smile on his face :D I'll add a link to it in her gallery when she posts it. And all the other commissions I've told her she should post. >_>

(As an aside, showing someone this picture and seeing how they react to it is a pretty easy way to tell if they've ever owned a cat.)
