I'm a little OCD and I like things to be clean, clean, clean. When I was using news paper and paper towels as a substrate it was very satisfying to be able to disinfect the tub and completely replace the newspaper every week. But I have since switched to cypress mulch which I like a lot more for humidity and aesthetic reasons and it's driving me nuts that I can't continue my old cleaning habits. I change it monthly but I still imagine the substrate as a cesspool of bacteria. I've thought about switching to aspen because it's cheaper but throwing out aspen every week seems very wasteful too me.

So I'm curious about what works for you. How often do you change your bedding and what bedding do you use?
