Brown bats sleep a lot — 82% of a day. So do owl monkeys, squirrels, and lions — they spend 50% of the day asleep. Then there are animals who hibernate but that's another story.

There is something very calming and soothing about watching an animal companion like a dog or a cat sleep. Those who don't have this luxury can find great pleasure in gazing at the sleepy ones in this enchanting children's picture book written by Giovanna Zoboli who has created such lyrical lines as:

"Hushaby, hushaby, beds in the trees
Bird in the hammock sways soft in the breeze.

Monkey sleeps snug, wrapped in his pajamas,
with no teddy beside him, just his banana."
