  • No dog cat feeder
    Patent number: 6588367
    Abstract: This invention is a small animal feeder that physically restricts access to food by medium to large size animals. It is comprised of a 12 inch cube of cardboard with an extra elongated front forming a vertical 3½ inch silt. A plastic feeder tray filled with food is inserted inside. It is the size and shape of the front opening that functions as both the barrier to medium to large size animals while allowing unlimited access to small animals. Currently used or patented pet feeders do not discriminate between medium to large size animals and smaller animals where access to dispensed food is concerned.
