Here is Rienzi's mat after he decides he's vacuumed all he can. He does a pretty good job picking up the dropped food. If he were eating on dirt or in a bedded stall, he would pick up a lot of debris with each meal. He is still pushing a lot of food off the edges of the mat, so we will need to dedicate two mats to this particular feeding station.
The remaining mats will be cut into triangles that will fit in stall corners below the feeders. We'll still need to sweep up around feeding stations after meals, but this should make the job much easier in addition to providing a little more peace of mind concerning what is going into residents' stomachs.
