The Havana, called the Havana Brown by some registries, was developed in Britain in the 1950s by pairing chocolate-carrying Siamese cats with black domestic shorthairs. The result is a glossy, warm chocolate coat, brown whiskers to match, green eyes, large forward-tilted ears and a squared-off muzzle on a moderate, muscular body that typically weighs 6 to 10 pounds.
Havanas are often curious, people-focused cats that like to be part of whatever the household is doing, sometimes reaching out with a paw to investigate. Many are talkative, in a softer voice than a Siamese. In Boise, that sociable streak fits homes where someone is around part of the day. The breed is genuinely rare, so most adopters will meet brown shorthaired cats or Havana mixes, and each cat's personality can differ from the breed description.
