Abstract

An animal feeder and method of use is described herein. The animal feeder is configured to distract, calm, or occupy an animal for an extended period of time. The animal feeder includes an elastomeric body having an obverse side and a reverse side. The obverse side includes a feeding section having a plurality of nubs. The plurality of nubs are configured to slow an animal's ability to lick food therefrom. On the reverse side is one or more suction cups to suction the animal feeder to a surface to secure the feeder system in a single location. The animal feeder further includes a guard extending laterally from the feeding section to keep the surface below the guard free from saliva, drool, or slobber from the animal.
