Tonkinese cats

Tonkinese are nowadays said to be hybrid breed even though tonkinese coloured cats live are common in south east Asia. Tonkinese breeding program began in 1965 in Ontario, Canada, where Margaret Conroy mated burmese and siamese cats. However first known tonkinese was Wong Mau, cat that that helped to establish another breed - burmese. Burmese went different way when there was darker kitten in the litter by Wong Mau's kitten. Breeders found that new colour much more interesting and concentrate on this.
Similarly to burmese we have two types of tonkinese - american and european. American tonkinese are in type much like european burmese - they have round head, short nose and dominant nose break. Their body is cobby in contrast to european tonkinese. American tonkinese are bred in only four colours - natural (brown), champagne (chocolate), blue and platinum (lilac).
Tonkinese was preliminary recognized in 1991. And their type is similar to siamese of old type. And european tonkinese comes in much more colour than her american relative. On top of four colours known in US we have also red, creme, caramel tonkinese and 5 tortieshell colours - brown, chocolate, blue, lilac and caramel tortie. All these colour can be also tabby.
And all these colour could be in three different shades - solid (same tone as burmese), mink (tonkinese) and point (same tone as siamese). That means we have 72 colour combinationes for European Tonkinese.
Tonkinese are recognised by following cat associations CFA, CCA, ACF, AACE, ACFA/CAA, TICA and GCCF. The most common organisation in continental Europe - FIFE don't recognise them yet. They claim it's because they can't be purebred. When mating two mink tonkinese, you never have only mink kittens but also kittens of burmese and siamese colour. Often it's misinterpreted that they give birth also to burmese and siamese kittens which isn't true, because their kittens have different type. They're tonkinese and only comes in burmese and siamese colour.
