The Tonkinese is a cross between a Siamese and Burmese and carries the best of both breeds. They are active without being over the top, extremely curious, and very loving.

They come in seal, chocolate, blue and lilac with three coat types, seal, which is dark points on a pale body, the same as the Siamese, solid, dark points on a dark body and mink, a contrast between a seal and solid.


Originally called the Golden Siamese, the Tonkinese is a hybrid created by crossing Burmese with Siamese cats. While the modern Tonkinese is a man-made breed originating in America, there is evidence that it has been in the West for quite some time prior. Mr Young of Harrogate is said to have brought a Copper cat to England. This cat is described as a “chocolate variety of the royal Siamese cat, rich chocolate or seal, with a darker face, ears, and tail; the legs are a shade darker which intensifies towards the feet”.

Tonkinese cat

In 1930, Dr Robert Thompson imported the now-famous Wong Mau, who went on to become the matriarch of the Burmese. Wong Mau is the first known Tonkinese.

Tonkinese in America:

A Burmese breeder by the name of Milan Greer of New York decided to cross a Siamese to a Burmese to determine if the offspring would breed true. Greer mated Anyo, his male Burmese to a chocolate-point Siamese who belonged to breeders Genevieve Gibson and Helen Arthur. Five generations were produced from the resulting offspring, proving to Greer that they did indeed breed true. Once confirmed, he stopped breeding these Golden Siamese and went back to his Burmese, however, these Golden Siamese had already proven extremely popular.

Tonkinese in Canada:

Then in the 1960s, a Canadian breeder by the name of Margaret Conroy crossed a seal-point Siamese to a brown Burmese. She was trying to produce a cat which had the best traits of both breeds. It is Margaret who wrote the first breed standard for the Tonkinese and registered them with the Canadian Cat Association (CCA), which is why you may often read that the breed originated in Canada. While not technically correct, Canada was the first country to register the breed.

Edith Lux is the breeder credited with changing the name from Golden Siamese to Tonkinese. Its name comes from the Gulf of Tonkin, which is close to Burmese and Thai (Siamese) territories.


Tonkinese cat

Words used to describe the Tonkinese include medium and moderate. There is nothing extreme about the appearance of this breed.


Medium in size and muscular, the body lacks the exaggerated length of the Siamese. They are surprisingly heavy when picked up.

The legs are long and slim, and hind legs are slightly longer than the front legs.


Wedge-shaped with the appearance of an equilateral triangle. The muzzle is blunt, and there is a slight nose break. The ears are oval and reasonably large. Eyes are almond-shaped, blue or aquamarine.

The coat is short and close-lying. It feels silky and soft. The colours are midway between the Siamese and the Burmese, they have clear points, but the body is darker than that of the Siamese. It can come in three patterns:

  • Pointed – Dark colouring on the extremities such as the face, ears, limbs and tail on a white to cream base.
  • Mink – This colour is an intermediate between pointed and solid. The points are still clearly visible, but the base is darker than that of the pointed Tonkinese.
  • Solid – The darkest of the three patterns, the solid colour is similar to that of the Burmese, with much less of a contrast between the points and the base.

The colours are referred to as mink, and the four basic colours are; Seal, Chocolate, Blue, and Lilac.

Tonkinese genes:

The genes responsible are incomplete dominant, that is they carry both the genes for the Siamese (cs) and the Burmese (cb). So a Tonkinese genetically is cs/cb (we inherit one gene from each parent). Neither the cs (Siamese) or the cb (Burmese) is dominant over the other, hence the term “incomplete dominant”. The first generation of a Siamese/Burmese crossing will produce Tonkinese kittens (cs/cb), if those kittens are mated, the offspring may be Siamese (cs/cs), Siamese (cb/cb) or Tonkinese (cs/cb). So, if you mated a Tonkinese to a Tonkinese, you would typically expect to get 50% Tonkinese, 25% Burmese and 25% Siamese.

As with most breeds, the male Tonkinese is usually larger than the female.


Tonkinese cat

Tonkinese is an extremely intelligent breed of cat who is active, playful, mischievous, friendly, and loyal. They are people-oriented and don’t like to spend long periods on their own.

They get along with people, children, and other pets. Due to their intelligence, they can be taught to do tricks such as play fetch, and many are happy to walk on a lead outdoors.

Tonkinese can be talkers, but not as much as their Siamese cousins with a sweet and quiet voice.


The Tonkinese is a healthy breed with no known genetic health problems.
