Product review (5 stars): Ferret Fun and Exercise!
This product should be marketed under ferret products because it is the perfect thing for ferret owners to purchase. Ferrets are natural burrowers, my dad tells the story that back in the 20's his father used a ferret when hunting rabbits to chase rabbits out of their burrows.  I purchased 4 sections.  The sections come with connectors.  Two sections connected together is long enough to go from the top of the stairs to the bottom.  My two ferrets will climb up and down, chasing after each other and get tons of exercise.  They use a section to climb in and out of the bath tub, and another section in the tub for some rough house playing.  People are entertained as they watch what goes on inside the tubes as one ferret crawls through one end and one ferret crawls through the other end and they meet in the middle.  They have a face off and one is forced to back out.  This is way better than what you can get at the major pet stores for ferret exercise and fun.
