Why is it so amusing to watch cats do dumb stuff? Like riding on one of those robot vacuum cleaners, it doesn't make any sense why the cat would be on one of those yet it is so fun to watch. Especially when that cat is dressed like a shark and chasing a duck around the room. If that sounds like a great video for you check it our below. And if your more of a dog lover don't worry, there's also a dog dressed as a shark to keep you on your toes. Just be careful jumping into the shark tank!
