They certainly are fun and amusing to watch.
I admit that I enjoy squirrels...it is as if there is a little thought bubble above their head, and you can almost see the gears spinning.
I saw one a while back trying to cross a busy road a rush hour by doing a tightwalk journey on a powerline above the road...no problem...I was really impressed, but he fell, plopped on the road in front of the car in front of me, bounced, and IMMEDIATELY made a beeline for the side of the road and made it!
Now THAT was impressive!
