11. Fox Squirrel
This squirrel looks like it ate an acorn, or three, whole! But no, most of her belly is full of baby squirrels; on average, two or three of the cute ‘lil things. The gestation period lasts about 45 days and sometimes, on rare occasions, mama squirrels can have up to seven little ones. The hump on her back is about the size of her belly, and it looks like she’s resting her little paws right on top of it!
