The Egyptian Mau is a relatively new breed to the United States.  However, the Mau was a valued household member of Egyptian royalty.  In fact, there are pictographs and statues of these cats in the tombs of the royals.  The bone structure of the Mau face is unique; the rear legs are longer than the front legs and there is an extra flap/pouch of skin between the rear legs and the groin thus allowing the Mau to run at greater speeds.  They have been clocked at 30 to 35 mph.  They are quick to express their wants, are very devoted to their owners and can be very sociable.
