  • Patent number: 5921596
    Abstract: A kitty litter scooper that allows users to clean out litter boxes without having to stoop and bend over, and allows users to move litter boxes without having to physically touch the litter box. The scooper includes a telescoping long handle that attaches to a receptacle by an adjustable swivel connection that allows the handle to be fixed to the receptacle at different angles. The receptacle has parallel slot apertures that are sized to allow granular materials such as sand and pet litter but nothing larger to pass therethrough. The receptacle includes a rear hook portion which can be used to hook over or under an edge of a litter box to move the litter box from underneath tables, furniture and the like. The receptacle further has an extended planar lip portion having a raised wedge thereon which helps keep clump contents within the receptacle.
