Page "Burmese (cat)" Paragraph 8

However, due to the extensive breeding with Siamese cats that had been used to increase the population, the original type was overwhelmed.

CFA, the leading US cat registry, suspended recognition of the Burmese as a purebred cat on May 8, 1947.

Other American cat registries continued to register the Burmese in America.

In 1954, CFA lifted the suspension, and Gerstdale's The Princess of Re-Ru and Hassayampa Spi-Dar of Regal were entered in the Foundation Record of CFA.

In 1958, the unaffiliated breed club, United Burmese Cat Fanciers ( UBCF ) wrote a single standard that was to be used for judging ideal Burmese in all registries.

The UBCF standard has remained essentially unchanged since its adoption.

This standard is used in all American registries, but European regestries maintained their own standard.

Recently, The International Cat Association ( TICA ) and CFA clubs have started holding shows in Europe and use the American breed standard for judging the Burmese in Europe.

During the early period of breed development, it became clear that Wong Mau herself was genetically a hybrid between a Siamese and Burmese type.

Such hybrids were later developed as a separate breed, known today as the Tonkinese.
