OK, not exactly no mess, but certainly minimal. Awhile back I got three of these from our friends at The Rabbit Haven and they do work remarkably well. Hinged on the bottoms the front wire is bent to fit the sides of the box and is velcroed to the back. There are holes cut in the grid for feeding. When un-velcroed the top swings out and forward for easy hay stuffing. Anything that makes cleaning easier and keeps hay from causing GI stasis in my vacuum gets the maximum number of stars.
