My cats decided that it would be a good idea to use my former dryer exhaust hose as a ladder.  They are a bit older now and I needed to do laundry and not fill the house with moisture/fuzz.  So far, so good.  As a note, make sure you have wire snips as I doubt that you'll be able to cut through the wire easily with scissors.
