i was walking past a park earlier when i heard a wierd growling noise, and saw a squirrel halfway up a tree staring at the ground swishing its tail like mad, i thought there must be a cat at the bottom or something so i looked over the wall to see the bottom of the tree and there was nothing there then i realised it was the squirrel making it as it was still doing it. it baffled me for a while coz id never heard a squirrel before and was suprised such a little thing made such a crazy noise has any1 else ever heard one?
