Pull the other one.
If dressing up as a big furry animal is a massive turn on for you (and why the hell wouldn't it be?), we have some great news for you. Courtesy of ThinkGeek humanity can now purchase the Twitchy Kitty Electronic Tail; a clip-on tail that twitches and swings just like a real cat's. Phew.
Powered by four AA batteries, the animatronic tail simulates the movement of a cat's appendage, allowing you to clip it to the back of your trousers (or indeed your huge cat outfit) and pad about the place being all cat-like. Like this guy did:
Future versions are planned to be able to stand up on end and puff out, like when a cat gets scared. Oh, and as the video displays, you can get the ears as well. What a wonderful world we live in, eh?
