They're cute, cuddly, mischievous and all over the Internet: Cats seems to be the undisputed kings of the web video jungle -- so much so that last week one museum hosted an Internet cat video festival. Below, we've listed 20 of the most-watched cat videos on YouTube, each of which has garnered millions, if not tens of millions, of views.
Of course, not every feline escapade caught on tape is a charming one; when researchers at the University of Georgia attached small cameras to more than 50 cats, the videos they gathered showed cats killing birds and engaging in risky behaviors like crossing roads and eating or drinking substances away from home.
