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.
Why does your cat wash your hair or face? The first thing a kitten experiences, even before it can see, is its mother licking and washing. Grooming is a demonstration of love and caring. So, if your cat occasionally washes your hair or licks your face, he is showing you his acceptance and caring of you as a fellow feline.
