I had to look that kitty up...The toms weigh about 5 pounds, so they are much smaller than our domestic cats.
Thank you for posting.
They are small, but beautiful. Kind of remind me of American Shorthair. I have 4 Siberians. 2 are 8 lbs and small for the breed, one is 12 lbs, and one is Sumo wrestler size at 14 lol.
