Can please somebody say if in this gme MC gonna be able to impregnate furry girls(that right now in game and gonna be in future) and have kids with them. Like they gonn appear un game so we can see how his furry kids gonna be look like?

Yes, the PC can impregnate beasts but not cross breeds. The children won't be beasts though. If a human and beast mate a cross breed  comes around. Only human x human or beast x beast results in pure breeds.
