Certain animals or wildlife exist in Erfworld that are not part of a side. They are not units, but can be interacted with by units. One such interaction is hunting, by which means a unit can create provisions to be eaten on a later turn in lieu of popped rations.
Pigeons were made into Pigeon Pie. Rats were speculated to be food (even if not seriously) by Jillian. The pigeons were presumably collected/hunted by Bogroll. So, are they units that can be attacked? Or is this "hunting," and do they provide Rations outside of what is popped? Will this save a side Shmuckers?
