Hi everyone! I've go my baby now in a cheap/borrowed cage. I ordered Urban Shop Snap-It Plastic Cube Shelving Unit http://www.walmart.com/ip/Urban-Shop-Snap-It-Plastic-Storage-Set-of-6/20709799 I'm still waiting for it to get here (hurry up shipping!) since it has solid walls I'm not planning on adding the Cloroplast. I'm planning on making fleece liners. Can anyone tell me if you recommend 2x3 squares, or bigger? smaller?
