Why does Minnie sometimes go under a table or a bed to fall asleep?

Maybe it just wants to be alone!!! Or if somebody's bothered it when it's sleeping and woken it up... Just a need for privacy.

Cozier, too. My wife makes a little nest out of a blanket, and her kitty loves to sleep in it.

It wants to go where it won't be disturbed. Mine doesn't hide very often to sleep because I seldom wake him up, but many cats will find a private place to lay for their catnap.
