You really never know, especially with the way mice are randomly bred. Who knows what genetics they may be carrying. I've had plain PEW's throw god knows what weird colored babies, so you've got me.
That male is a pretty satin fawn/white. I have a few babies like him, as well as some long-haired black/white satins. I'd really like some frizzies(had one but she had a weak immune system).
Sarah (SarahMB) is graciously letting me borrow her hairless mouse that mysteriously popped up in one of her litters. So we'll see what type of genetics that little female is carrying. Should be interesting!
