Tonkinese are a domestic cat breed produced by crossbreeding between the Siamese and Burmese. They share many of their parents' distinctively lively, playful personality traits and are similarly distinguished by a pointed coat pattern in a variety of colors. In addition to the modified coat colors of the "mink" pattern, which is a dilution of the point color (as in watercolors), the breed is now being shown in the foundation-like Siamese and Burmese colors: pointed with white and solid overall (sepia). They are also now designated a natural breed, as their history has now determined them to have been extant since the 14th century[citation needed].
The best known variety is the short-haired Tonkinese, but there is a medium-haired (sometimes called Tibetan) which tends to be more popular in Europe, mainly in the Netherlands, Germany, Belgium and France. Source: https://en.wikipedia.org/
