Does anyone else use paper (news paper or blank newspaper print)? I found that Wally World sells a nice drop paper (very thick and absorbent) for painting. For RBI cages you can just cut it to width (assuming you have the smaller cage) and it comes in rolls of about 500'. That lasts a while and looks nice (medium to med dark brown) for only $7.99 a roll. Any other cheap sources of paper ideas other than ugly local news paper with election news all over it?
