Well, I'm glad I don't live in the environment the moles live in then...

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

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.

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

Cowlick doesn't go against what the post is saying

Their hair can lay in any direction at anytime

It's not saying that you can make their hair all perfect in any direction.

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

Few people have gotten close enough to a shark to pet it. If you could run your hand from a shark’s head to its tail—not that you should—it would feel smooth, almost like suede. Reverse direction and it’s rough like sandpaper. Viewed under a microscope, shark skin is composed of ribbed, dragonesque scales layered over each other like shingles on a roof. These structures, called dermal denticles, are more like teeth than skin
