  • Patent number: 4970987
    Abstract: An animal waste collection and disposal device for separating animal waste matter from granular litter material is disclosed. The device includes first and second sections, each of which has apertures which are sized and configured to permit the passage of granular litter material but substantially prevent the passage of waste matter. The first and second sections are connected by a connecting means which pivotally and slidably connects the first section to the second section so that the sections are capable of pivoting relative to each other between an open position and a closed position and slidably moving relative to each other between the closed position and a waste matter dumping position. An animal waste collection and disposal apparatus including the aforementioned device and a litter box specially designed for use with the device is also disclosed.
