Cat litter box: Get a plastic container and cut a hole in the front. Make sure the box is a little bigger than the litter container itself so that it can trap the litter inside the box. Put a foam mat at the bottom, a few hooks on the side for items such as the scooper and attach a motion light to the back. Thats it! The smell and the litter will stay trapped in the box and you will have everything you need in one spot!
