Abstract
Abstract A pet feeder is provided comprised of a durable bowl-shaped holding receptacle having an upper rim and exterior sidewall, and a thin resilient integral liner contoured to secure close-fitting contact with the interior of the receptacle and to extend over the rim and downwardly onto the exterior sidewall. The receptacle is elongated, having short and long axes of symmetry, and its sidewall is provided with opposed vertical and horizontal recesses. The vertical recesses permit finger insertion to facilitate removal of the liner. The horizontal recesses, in conjunction with the elongated configuration of the receptacle, cause the liner to be positively seated upon the receptacle.
