The Havana, also called the Havana Brown, was developed in Britain in the 1950s from chocolate-carrying Siamese and black domestic shorthairs. It's easy to spot: a glossy chocolate coat, brown whiskers, green eyes, large forward-tilted ears and a squared-off muzzle. At roughly 6 to 10 pounds, it's a medium, muscular cat without extreme features.
Havanas are curious and people-focused, and many pat at things and people with a paw to investigate. They talk, but more softly than a Siamese. The short coat sheds little and needs only light brushing. Because the breed is so uncommon, many adopters will meet Havana-type mixes or brown shorthairs, and those cats can share the same sociable streak, though no cat is guaranteed to match a breed description.
