The Napoleon is a new breed - a hybrid breed which means they have crossed two existing cat breeds together to form a new look.  Crossing the Munchkin breed (the original short-legged cat breed that looks like a domestic cat) with the Persian Breed Group  (which includes Persians, the Himalayans, and the Exotic Shorthairs)  resulting in a cat that is short-legged BUT....has the look - that sweet round baby doll face of the old timey "traditional" Persians of years ago.  They are produced in two versions - those that are called the "standard" which is the short-legged variety - fit for a showhall and possesses both renown features AND the "non-standard" version which has that same sweet baby doll face but has a regular leg length.

The short cute legs do not even begin to hamper mobility but it does encourage this little "prairie dog" perch that they are known for and they may have a bit of a waddle when they walk. Napoleons are a people-pleasing breed with a sweet even tempered disposition - lively enough to entertain with their antics but at ease when lying in the crook of your elbow.
