Fun fact, basically all of the US Russian Blue stock was cross bred with Siamese lines during WW2 to prevent inbreeding. Almost all of them carry recessive color point genes so you’ll see lavender point kittens out of purebred RB breeding occasionally.
Also Lynx Point Siamese is missing. One of the best cats I’ve ever had.
