As far as I know, KittyCatS doesn't make this particular "breed" yet. But it sounds like it could be a fun breeding project to try to make your own version of the Forest Cat
Or try to find one!
I guess start with some research into the Fur coat and color and go from there. Also a "fluffy" tail like a curious, plush, mysterious, swanky, fussy or posh would give the look of longhaired. Then just find your ears, eyes and whiskers.
