stupidity?
Me too. Once my cat was playing with some catnip mouse, so I threw it at the glass door, he jumped at it, and slammed into the door.
Once, my dad was terrorizing the poor animal with a vacuum cleaner hose, and drove him onto the windowsill. His eyes were all big and his tail looked like a wire brush, HAHAHA. He got so scared he jumped at the window and knocked the screen off, frame and all.
