I had a black racer idling across my yard when my cat, Hobbes, discovered it. He was following it so intently I was worried he might decide to attack it. Being more concerned with him harming the snake than the snake him, I unthinkingly went to pick him up. You can see where this is going can't you? Yep, Hobbes turned into a mini-tornado of teeth and claws. Shredded me from elbows to fingertips. I dropped Hobbes and he went right back to the snake. So, of course, not learning my lesson the first time, I had to go and try to pick him up again.
They think the cucumber is a snake.
