A first zone of the top surface of the stand includes an upwardly convex ring that laterally surrounds a respective bowl receptacle. A second zone of the top surface of the stand laterally surrounds the first zone, except as interrupted by a finger notch. Each bowl has a peripheral lip with a lower surface formed as a downwardly concave ring that is spaced over the upwardly convex ring of the stand. An edge of the bowl rests on the second zone at a location below the upper limit of the convex ring, thereby supporting the entire weight of the bowl and its contents on the stand. A base of the stand cooperates with upstanding ribs in an elastomeric mat to prevent lateral movement of the stand and to prevent rotation of the stand around the stand center. Compositions and shapes of the stand, bowls and mat are chosen to make them easy to clean and to reduce bacterial and fungal contamination. ## Claims ### Claim 1 A pet feeding system comprising: a stand having a front, a back opposed to the front, first and second sides joining the front to the back, and a top connecting the front, back and first and second sides, at least one sidewall of the stand extending downwardly from the top and terminating in at least one stand base;
