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 cat known for one look: a glossy, warm chocolate coat, brown whiskers to match, vivid green eyes, large forward-tilted ears and a distinctive squared-off muzzle. Its moderate, muscular body has no extreme features.
Havanas are often curious, people-focused cats that like to be part of whatever their household is doing, sometimes reaching out with a paw to investigate. Many are talkative in a softer voice than the Siamese. The breed is genuinely rare, with only a small number of catteries keeping it going, so most adopters will meet brown shorthaired cats or Havana mixes rather than a registered Havana.
