LOL indeed...when we built our outdoor adoption room for the ferrets, my husband and I went to elaborate measures to safely install a system of tunnels on one wall of the room using heavy duty 4" dust hose. Many holes were drilled to assure the braces for the clear tunnels were deeply anchored in the walls. We thought it looked splendid and the ferrets seemed to get a kick out of it. Then the "Power Poof Girls" came from the laboratory in Cali and they just never really grasped the concept I guess. Once they figured out the tube system was safe to play in...they decided it also made for a fabulous place to toilet...and they left little presents of thankfulness at every bend in the tube! As you can well imagine, there is no way to clean out 10' sections of tubing attached to the wall....so down it came, and never went back up. Ah well.
