Ferret Super Thru-Way is for ferrets that love to tunnel, so this is the gift your ferrets will love to play with for hours. Tie it in a knot or two for extra ferret fun. Ferrets love to play in and outside the Super Thru-Way. For an extra kick, buy two and lay them side by side for the most exciting race in years. Drape them over things (steps, chairs or yourself) for 3-D entertainment. Super Thru Way is 15 feet long.
