But it’s not completely covered in fur. A partially hairy sphere doesn’t need a cowlick.

A topological sphere so unless moles are actually a torus then it's still not possible.

I dont remember learning about moles in math. Chemistry, yes, but I don't think moles care much about topology.

However, if we assume an ideal mole in empty space with no air resistance, we would see how they have this property: their hair follicles would, in the absence of outside interference, stand straight up. So, its technically more accurate to say that every direction of petting a mole is equally wrong.

It's very short and perpendicular to the skin. It feels like velvet.
