Here is a pretty good website on Korats.

Korats are wonderful, smart, amazing cats. I still miss mine!
How you raise a cat is a lot of it, too. We had a one in a million kitty with the Korat mix and his sweet, loving, completely tolerant of anything temperament, and then we managed to train one of our next kitties (a pair of brothers) into a very similar way. His brother’s about 80% of the way there but skittish...still has the same underlying gentle trustworthiness, tho.
