We've seen the cats from Cat Navi Desk learn to ring a bell for food, topple dominos, and do trick shots. Now they are initiating marble runs! Watch as they set off a series of increasingly more elaborate marble runs, culminating in a full-size pinball-like contraption that must be so much fun to play with!
This is ingenious. Their human took a cat's natural inclination to knock things off and leveraged it into entertainment for the internet audience that loves both cats and marble runs.
