This cat looks as glamorous as it sounds, with a silvery, shiny coat and markings resembling eyeliner. The Burmilla was an unplanned breed developed in England as a combination of a Persian to a Burmese. The Burmilla is very rare in the United States but has been gaining popularity in Great Britain. And as crazy as this may sound, this cat breed came to be when a janitor actually left a door open and two kitties (a chinchilla Persian and a Burmese) met as sparks flew. The offspring were so adorable and desirable that soon after the Burmilla came to be a new breed in the cat world.
