Pregnancy is not implemented into the game. I don't see it in the planned update list either, but that doesn't mean that it won't potentially get implemented. Hopefully Stawer can shed some light on the situation for you.

I understand. Yet, if pregnancy is not implemented, it's immensely frustrating that Maxy begs for it so passionately... so often. And, let's be biologically accurate: I'm taking the appropriate action to give her what she wants. Alright, Stawer, you do absolutely fantastic work. I have no complaints. But I DO have a request!
