This strange post is for anyone that has ever wondered what JD’s belly looks like.
A genetics lesson - A black tan mouse is one that is black on top and tan on bottom. The lines between colors should be very straight and well defined. Ideally, they would be much darker than JD’s tan. A broken tan often has white splashed onto the belly or chin, like JD shows here. Me personally, I like these “flaws”. I think they make his belly even cuter.
