I used to use cypress, then it got too expensive so I nixed the look and went for aspen SOOOOO MUCH BETTER belive me it was easier to work with definitely and half the cost. But when I switched to tubs I went unprinted newpaper (packing paper) and I dont ever plan on going back. It works perfectly, switches easily, and you dont have pieces of friggin wood all over your room.
Oh and in your shoes, I should mention that too, it stinks when you put on your shoes and it just happens that there was bedding in it, god that was horrid, and almost like once a week.
