There's a lot of people adopting animal characteristics for costumes - right? Lots of bunny ears at Easter for sure and reindeer antlers at Christmas. But what about tails?? The latest trend in creating tails for humans is to make them animatronic - so that they resemble actual animal movements. The technology is so advanced now that the movements are programmed and controlled easily by a smartphone app.
While the company making these says a lot of their business does come from people looking for a costume, they also have customers who are part of what's called the "furry community" - those who dress up and act like animal characters and take it all quite seriously. So just be careful who you make fun of that's sporting a tail out the back of their outfit - you just might get clawed.
