I change the paper almost daily, so it would be kind of a waste. Two sheets is just enough to catch the poop and the solid part of the urates so I don't have to scrape it off. I just flip the bin over above my outdoor trash can and everything falls out. Then a quick spray and wipe with a disinfectant and I'm good to go again. I would like to try the white butcher paper that I see some breeders using because I like the sterile clean look, but I stick with newspaper because it means I am not purchasing something that I will just be throwing away(I use the supermarket newsprint ads that get stuffed in the mailbox everyday). My BP's are all very "green" conscious, lol.
