Sorry, 'pup! As matildaben pointed out, it's a very sweet video about a really good-natured cat. The people who made the video (I'm assuming the people who live with Charley) also include a message about how the symptoms are really only limited to the cats' muscle control and that they aren't in any pain. They also encourage people to adopt kittens which exhibit such symptoms instead of letting them be destroyed since it doesn't seem to affect the cats' quality of life very much.
