Always gotta factor in the magic separating tail thing. If you'd ever seen a squirrel almost make it past a car that was heading for it, you'd appreciate how efficiently those tail segments come off. I once watched a squirrel racing across a street at top speed, trying to beat an oncoming car. All but a couple of inches of the squirrel's tail made it, and amazingly there was not even a momentary reduction in the squirrel's forward velocity, as the car's tire clamped down on the end of the squirrel's tail. I'm surprised your squirrel didn't land on your head :-)
