The "far east wood cat" reminds me a bit of "forest cats", except there are traits in there that make me think it's at least mixed with something wild (the rounded ears being a big one).
It's kind of interesting how much cat species can interbreed and even (very rarely, in the right circumstances) have fertile offspring that can cross back to one of the parent's species. IIRC, all cats have the same number of chromosomes, just some are moved around in one species, or turned off, or still active in the others. But just having a matching number of chromosomes makes crosses easier. So then it comes down to how different the actual genes are and size differences as to whether a pairing will produce viable, or even fertile, offspring.
