Just out of curiosity

So, I'm playing as a gray/kk wolf, looking for a 2-star mate (smaller litters preferred, lol). But I don't want another gray/kk wolf as a mate (from what I've heard from the community, it increases the chance of sickness and limits color options). I've been searching for a while and can't seem to find a black/Kk wolf that's 2 stars. Is it not possible for a gray/kk wolf to find one, or is this just a coincidence?
