I want to make a remote litter box I think. I am sick of the smell of litter (even clean and esp messy) and think that it would help. Once I get my iguana's cage done and my room all arranged I think I can fit one on the tray under the FN. There are already holes cut into the side of the cage with little plastic brackets to attach tunnels too (I believe they are Super Pet FerreTrail brackets). I don't want to buy a bunch of expensive ferreTrain tubes, so will a black pvc/dryer hose work (like the ones pictured in this thread) to give him enough grip for a vertical drop? I am afraid he will not use it too because he has been pooping in the corner of his bottom level (where the box is) so well for so long.... I am still undecided, but I am definitely considering it as it would give him more space and hopefully (?) keep toys and food out of the litter and litter out of everywhere else. I don't really have any fancy tools, or the $ for them. What is the best way to cut a hole in the tupperware?
