First of all, a tip of the cap to YouTuber 'GarrulousCrap' for giving his cat such an awesome name: 'Boo'. Sure, his own moniker could do with some work, but his feline friend's nickname is just right.
Anyway, Boo here doesn't like being alone. At all. In fact, when his owners are trying to get some sleep in their bedroom, he spends his time scratching under the door, grasping for attention.
But worse than that, he's found a way to make some noise. The door stop slinky-ma-thing on the other side is perfect for his paws to twang, resulting in a noise that can only be described as 'very annoying'.
Still, you've got to admire the ingenuity of the furry fellow - especially as his naughty habit have entered him into the Huffington Post UK Comedy 'animals behaving badly' hall of fame. Respect to that cat.
