Not sure, females grow 6-8 pounds and males are 8-10 pounds. Lucky ranged in the 8-9 pounds as a male so i think its a pretty universal number for slim cats.. she should come out fairly tall and slim with Korats being free from human manipulation in the age old trade of selective breeding for i guess it'd be hundreds to thousands of years. They werent allowed to be manipulated like that since they're sacred good luck charms in Thailand and only given as gifts, never sold (no idea if these traditions still continue and if they dont, dunno how long ago they stopped).
Infact, tbh, if it wasnt for her mutation we would think she was purebred cause she shows all natural faults in a Korat's fur (faint darker fur in spots and stripes along the coat, small tuft of white fur on the collar bone) and has the silver sheen which is the immediate indicator of Korat or another breed, and her eyes are changing from yellow to green which is part of their stage development. But polydactyl is a mutation common in cats from Eastern North America, mostly states side, and also England. They were removed from England however when they were deemed to not be a 'blue siamese' which was what people passed them off as and they were no longer allowed in shows. But they were brought to America in the 1970's and i have a sneaky bet she might of had a relative at the Hemmingway Museum. Its a museum and a home for cats who carry the polydactyl mutation.
er..
I love the Korats history, can you tell?
Anywho, sorry, lol XD
She's like i said pretty much a fake purebred in that she looks like a full blown Korat but has the mutation. So her other 'side' is undeterminable but it'd be something that'd be recessive. Probably not a tabby, i think that they're genes are pretty dominant but maybe a member of the siamese family. I dont know a whole lot of breeds that would be candidates but it would be definitely something that wouldnt be able to compete with the Korats genetic nature.
You can tell she was made for jumping to catch birds btw im sure from the pics of her stretching, she can jump as high as my bust, which is probably 4 feet from the ground. Im 5'5. And shes only 4 n a half months too, she has a lotta growing to do but shes gonna be a tall and long cat and she's pretty big for her age too, nothin' but muscle from natural breeding. All i can say to that end is thank god she doesnt use those legs of hers to climb up curtains XD Lucky did that all the time as a kitten, we'd have to get on chairs and pry him from the bar the curtain rests on.
