I used dryer vent tubing to make a circular staircase for a hedgie. Worked great, except he poops in there and it's pretty difficult to clean well. Just in the last day or so, I've noticed what I believe to be evidence that he is chewing on the tubing. This understandably worries me, and I wonder if other people have had any problems with this. Would switching to using the clear/tinted plastic stuff for ferrets work? It's almost the same stuff, but instead of being silver/metallic, it is clear plastic. I watched at first to make sure this guy wouldn't chew, and since he seemed to leave it alone, I didn't worry about it, but now I am worried again. I'll keep watching closely to see if maybe he's just going through a phase and will stop, as it's only the last 24 hours I've noticed him chew on it, but I wanted to hear if others have had this problem and how they solved it. Fortunately, we are just about to add on to the cage, so it's a good time to modify if need be.
