Yea, the fiber info has been changed for quite a while...but you still get single fibers right now from dusty sticks...though if you see a fox, would love to be proven wrong...but I do have a friend or two that will release a dusty stick in random places, and leave the fiber behind for those that want to pick it up.
Here's a pic of the fibre description. As Unique One said, the description originally didn't refer to foxes. We're still getting it from the dustbunnies released by dusty sticks.
I wish that a fox had left that fiber, but I am sad to say that it was me. I unleash my dusty stick at the tool vendor every day when I sell my wares, and I did so right around the time of your post.
