How Much Fish

How big would a fish have to be before a cat can't steal it? A Japanese TV show ran an experiment to find out. They left increasingly larger fish out for stray cats to find. The cats dragged off astonishingly large fish, and it's quite funny. The experiment was supposed to end when the fish got too big, but my theory is that all the cats of the area had eaten too much fish by then to consider it worth the effort anymore. But this experiment wasn't stringently-designed for research, it was just a cool idea for a TV show. If you don't understand Japanese, the relevant segment runs from 3:50 to about 15:00. I posted this more than ten years ago, but that copy of the video has been deleted from YouTube.
