The Chantilly-Tiffany or Chantilly/Tiffany, also known as the Chantilly or the Foreign Longhair, is a breed of cat derived mainly from cross-breeding long-haired Asians and Burmese. The breed originated in North America. This breed is considered distinct from the Asian Semi-longhair breed, the British variant. The Chantilly was thought extinct until the 1960s when two of these cats appeared during an estate sale.
