Abstract

A dish for holding substances that are to be consumed by an animal has a central portion forming a bowl and a peripheral region which slopes downwardly and outwardly from the rim of the bowl. An annular depression extends about the peripheral region to capture and retain food and the like which may escape the bowl portion due to the animal feeding. The bowl, peripheral region, and annular depression are formed integrally of molded plastic material. The plastic material may comprise a mixture of polyethylene, silicone, and parafin to form a hydrophobic, non-stick surface to facilitate cleaning. The dish is dimensioned with a low aspect ratio to resist tipping, tilting, and upset. An annular groove disposed about the circumference of the dish opens downwardly and retains segments of solid, resilient, high friction tubular material which are ground-engaging to resist lateral motion of the dish during feeding.
