Thought I would share this as it has just made my life that much easier . My original board consisted of 13" wide piece of plywood framed around with 2X2 so I could fill with litter. This did not work so well as it was a pain to clean. I read on here about using sand but didn't see myself scooping and sifting sand everyday. I bought a sheet of 4 foot by 32" white gloss hardboard panel at lowes. It is brown on one side and glossy smooth white on the other (think it is used for bathroom paneling) I ripped it in half on my table saw and ended up with two pieces 48" x 16". I laid these on top of the old poop board. The surface is so slick the poop does not stick to it. I scrap it off with a 5" wide plastic putty knife (so as not to scratch the finish) and into a bucket. I can scrape both boards clean in less than a minute. The sheet was only $11. Sorry no pic, I will try and get one in a day or two.
