    This is a mathematical problem with no solution, there has to be a cowlick on a sphere. Perhaps the mole avoids this problem by not being a sphere, where there is a possible solution

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

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

      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.

          Someone else covered it in another reply, but moles have bald areas. Hairy Ball only applies when it’s entirely covered.

          Edit: other comment

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

          Unless they wear a whig.

          they are however usually not hairy on the inside

      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.
