A foreign exchange hedge (also called a FOREX hedge) is a method used by companies to eliminate or hedge their foreign exchange risk resulting from transactions in foreign currencies (see foreign exchange derivative). This is done using either the cash flow hedge or the fair value method.
Sleeping on your face puts the top cat at the highest point on the bed, the primo location for keeping watch over everyone. Your more submissive kitty will probably sleep at the foot of the bed or in her own kitty bed in the corner of the room.
A cat lying on its back is leaving its belly exposed and vulnerable (to having some nasty critter rip the guts out). When a cat lies on his back and shows you his belly, he's saying that he trusts you not to attack him. And if he SLEEPS on his back, that means his level of trust for you is in the stratosphere!
