You have learned a very valuable lesson that most of us have to learn at one time or another: don't assume ANYTHING! Always read labels - especially on anything you've never bought before.
As for what to do with the wretched thing, contact a local wildlife rehabilitator and see if they'd like it. I understand they can use furs to comfort orphaned animals.
Get off the toilet, relax, and remind yourself that everyone makes mistakes. Everyone! Your mistake was, I admit, quite unusual, but whether it's a tail or a sausage, it's all really the same thing, isn't it? So take a deep breath and move on.
