The Havana, called the Havana Brown by some registries, began in 1950s Britain, where chocolate-carrying Siamese were paired with black domestic shorthairs. The look is unmistakable: a glossy chocolate coat, brown whiskers, green eyes, large forward-tilted ears and a squared-off muzzle on a moderate, muscular body that usually weighs 6 to 10 pounds.
Personality matters more than looks for a good match. Havanas tend to be curious and people-focused, and many reach out with a paw to investigate whatever you're doing. Their voice is softer than a Siamese's. The breed is rare, so in Louisville you're more likely to meet brown shorthaired cats or Havana mixes, and each cat can differ from the breed description. Lifespan is commonly 10 to 15 years, a long commitment worth planning for.
