Scott’s Must See Cat Video – No Kidding

We 'adopted' a kitten several months ago. I'm not really a cat person. It lives outside. I feed and water it multiple times a day.  It a pretty good cat. I took a quick video of the cat doing something I have never seen IN MY LIFE.

Can someone tell me why in the name of all things good and safe in the world is this cat SUCKING her tail?? It just look WRONG. And yes she is sucking her tail...i looked at it and her tail was flippin wet on the tip. I think she needs counseling. I may need it too.
