Wow, we like these food bowls attached to the tray. No mess, no fuss. The food bowls are built-in with the mat totally surrounding the area, so spills will stay within the mat area instead of all over the floor. The bowls are easily removed for a fill-up. The underside has non-slip nubs to stop the matt from sliding around while the dogs eat. They come in easy to match colors and are a great price. Purchase one today!
