How do they do it?

This is our cat, Gus, taking a mid-morning snooze - sound asleep.  Doesn't look too comfortable - at least, to me!!  I can't figure out how he squeezed himself into that small container.  He sure looks cramped!  How do they do it?  Personally, I prefer a nice big bed that I can sprawl out on.  But, then I am a human and not a cat!  Apparently, he enjoyed his nap because he stayed in that position almost all morning.  T
