I call my version "Room to Room" since the ferret enters the tube in one room, and exits in another part of the house entirely. I use the full 20 ft tube. I have another version called "Upstairs, Downstairs" where I stretch the tube the length of the stairs. Ferret is put in at top and slides, runs and bumps down the stairs in the tube. Having a second human at the bottom to redirect the excited dancing ferret back up the stairs is useful. Having multiple ferrets play is a blast, especially if one stops partway down, and tries to climb back up while another is on the way down. :-D Linda [Posted in FML 6380]
