He was sleeping on the back of a couch. I grabbed his back legs and shook them. He kind of kicked away because he doesn't like his feet being touched. So I grabbed them again... He'll usually get up and meow or swipe at me or something. His legs were just limp, though. So he was just lying there still... Then I kind of hit him on the belly a few times and still nothing. So now I think holy shit he's dead... Then he lifts his head up and meows... Jesus Christ...
