Chocolate cats are uncommon, because the gene that is associated with their lush mahogany coats is seen only in a small, select gene pool. All chocolate cats are descended directly from a single individual, a Havana Brown cat. The Havana Brown breed was created by crossing a black, blue, and color-point cats. Because of their specific and verifiable ancestry, chocolate cats of all shapes and sizes hold their personalities in common. They are intelligent, very friendly, and quite playful.
