Havana Brown is a cross between a Siamese cat and a domestic black cat. Their main distinguishing features are delicate chocolate color, narrow muzzle, and large ears.
It has nothing to do with Cuba and Havana and received the name for the similarity of color with the color of Havana cigars.
By the way, such breeds as Burmese and Korat also came from the same country.
They were positioned as Siamese, took part in the exhibitions of that time, and in England in 1888 they became winners.
