Maybe it's something to do with protection - nothing can get to you if you are enclosed?
That's exactly the reason.
As long as they can step into somethiing, whether a box, a bag, or under a rug then they will happily sleep or rest there.
Even if the other 95% of their body doesn't fit into said space.
But the more encapsulated they are the safer they feel.
