Product review (4 stars): Ferret fun!
I ordered these for my daughter to use in her ferret playpen for her three ferrets.  The ferrets LOVED them!  I liked that this was way cheaper then the exact same kind of thing from the pet stores.  At 8 feet long you could tie them in a knot and watch the ferrets go crazy!  I also liked that they were clear so you could clearly see just how much fun the ferrets were having.
