History
How did a brown cat of Southeast Asian origin, believed to offer protection from evil, come to be known as a Swiss Mountain Cat, and how did it then adopt the name Havana Brown? The full answers to those questions are lost to history, but what appears to have happened is that solid-brown cats of
Siamese type from Thailand were exhibited in Britain in the 1890s. Somehow during that time they acquired the moniker Swiss Mountain Cat.
In 1920, the Siamese Cat Club of Britain decided that brown cats without
blue eyes were no longer desirable, and that was that. Breeders lost interest in them until the 1950s, when a group of British cat breeders set themselves the task of determining the genetic makeup of a self-brown (solid-colored) cat. They eventually produced a male chestnut-brown kitten, the result of a cross between a shorthaiared black cat and a chocolate-point Siamese.
Russian Blues and
Burmese may also have played a role in the development of what came to be known as the Havana Brown (whose only connection to Cuba is the supposed resemblance of his color to that of a fine Havana cigar). But as it turned out, according to an article in the 1982 CFA Yearbook, the most successful and most often used breeding to produce a self-brown cat was between a black shorthair and a seal-point Siamese carrying the chocolate gene.
