There are marked differences between the Burmese breed recognized in Britain by the GCCF and that recognized in the USA, but they both had their origin in act called Wong Mau which was taken from Rangoon to the United States in 1930.It was mated to a Siamese and produced kittens that were normal Siamese, some with less distinct points and some that had more evenly dark coats. The latter became the foundation stock for the Burmese, which was recognized as a breed in1936. Burmese still carry some color restriction and this is often noticeable in kit-tens but becomes less so as they grow up.
