A pet feeding device composed of a horizontally upright serving container having an opening in its upper end and an inverted feed-supply container having an opening in its lower end, wherein the open ends are axially inserted in overlapped position and then attached to one another in response to relative movement between the containers transversely of the axes of insertion. A pair of tongue-and-groove assemblies or joints are employed to guide the containers during the relative transverse movement, the tongue component of each joint being integral with the overlapped end of one of the containers and the groove component integral with the proximate overlapped end of the other container. By moving the supply container transversely and rearwardly from its axially inserted position, the tongue components of the joints intermesh progressively mesh with the groove components until the supply container reaches its normal position of use at the rear portion of the serving container. Conversely, by moving the supply container in the opposite direction toward its axially inserted position, the components are unmeshed progressively to disengage it from the supply container.
