From what I've heard, is not eco-friendly, their tails are harvested directly from fur farms for the sole purpose of being sold as tails. If you're looking for real animal tails, Etsy is the best place online. Many of those shops are mindful with their preservation techniques, and many get their tails secondhand from either naturally deceased animals or scrap so that every part of the animal is utilized. Several Etsy shops also include images of the exact product you will receive, so you don't end up with a "grab bag" type of deal that you may or may not be satisfied with.
