If you have been thinking about becoming a furry, this will either be your first step or the finishing touch on your outfit. For just $35(USD), you too can learn to fear rocking chairs and the feet of oblivious humans.
This clip-on animatronic cat tail from ThinkGeek is powered by four AA batteries, and will swish back and forth as it hangs from the back of your pants, telling all of the other furries that you are feeling happy. The next version will likely simulate other cat moods, like your tail getting bristly when you get scared.
So there you have it. Your furry outfit just got upgraded. Hey, stop licking yourself!
