Lilac Tonkinese is not in my cat handbook.
My Snowy is a mix, definitely Siamese, not seal or chocolate. He resembles the Blue Mink or Platinum Mink Tonkinese in my book the most.
His coloring is a smoky color, like silver mixed with brown. When he was a baby he almost looked pink, I guess it was his skin tone.

I still want to get a chocolate point boy. I have my paper work in at Siamese cat Rescue. I hope I see one soon...
