My young cat does the night crazy thing. It doesn't matter if you are in a couch or a chair, if you are in the flight path, you will be bounced. Having a cat hit your belly at Mach 10 hurts, big time. And by the time you react, he is long gone...
This same boy has a water fetish. But not water in his bowl, that would be much to easy. He likes water in human cups, and he likes testing to see how deep it is. So paw goes in first, then head. This generally results in a large spill. I was watching TV one night, set down a 32 oz cup of ice water, walked to the light switch, and before I could turn to light off, the entire cup of water was down. Because of the full cup, the wet cat jump and the angle, I got to clean water off the couch, coffee table and floor. Dratted beast!
This beast is black, and we have a gray one. They protect the house by guarding the stairs. Four steps from the bottom, and two steps from the top, they lie their little bodies, booby trapping the stairs, all night long. One day, my crumpled body will be found at the bottom of the stairs, where I have fallen, after touching cat fur with my bare foot, spinning to avoid stepping on the cat, and tumbling to the bottom, hip dislocated by the spin, head broken by the fall....cats laughing at the top.
