The Burmilla is a breed of domestic cat which originated in the United Kingdom in 1981. It is a cross between the Chinchilla Persian and Burmese breeds. Standards were produced in 1984 and the breed gained championship status in the United Kingdom in the 1990s. Burmillas are medium-sized with muscular bodies, round faces, short muzzles and tend to weigh between 8-10 lb. A burmilla's eye color is usually green, although some cat societies accept blue (and yellow eyes are permitted in kittens).
