Two guys in an Asian country (Philippines perhaps) wanted to rescue a cat who had fallen into a deep hole which must be at least ten feet deep. The walls are vertical and made of sandy soil and bricks. The cat races up this vertical wall as if he is on the flat. No doubt the nature of the surface helped. It allowed the cat to get a grip with his claws. Perhaps the fear of the approaching rescuer motivated the cat to take drastic measures. He wasn’t sure about climbing the wall until fear took over and he ran up the damn thing!
