Notes
A phenotypically similar cat is recognized by the GCCF as the Suffolk Chocolate. The Suffolk is NOT the same as the Havana Brown. The standard for the breed is different and the cats used for outcross to develop the recently created breed is different from those found in the Havana Brown. The registers CFA, TICA, ACFA and LOOF all use the same breed standard for showing and breeding the Havana/Havana Brown Cat. The Suffolk Chocolate is not allowed in the breeding lines of the Havana Brown in any of these registers.
Domestic cat (Felis catus)

The Havana Brown was the result of a planned breeding between Siamese and domestic black cats,^[1] by a group of cat fanciers in England, in the 1950s. Early breeders introduced a Siamese type Russian Blue into their breeding. However, using current genetic testing, it is believed that almost none remain in the gene pool.

It has been documented that self-brown cats were shown in Europe in the 1890s, one name given to these was the Swiss Mountain Cat. These disappeared until post-World War II, with the most likely explanation that the Siamese Cat Club of Britain discouraged their breeding.^[2] The Swiss Mountain Cat was never used in the breeding programs of the modern Havana Brown. However, they likely share genetics inherited from the Siamese.
