  • Patent number: 6234549
    Abstract: An improved hand-held two-stage cat-litter scooper tool critically configured to more effectively segregate and lift-away wet cat-litter, without causing migration into, or disturbing clean dry areas. The planar leading-edge of the scooping-blade portion, is formed to either a 90-degree triangular, or transversely-square, plan-view shape; either shape thus able to project closely into the corners of a conventional cat-litter box. The rear portion of either scooping-blade includes an approximate 40-degree transverse-bend, creating an aftward containment-bowl area, effectively holding wet cat-litter when the rearward projecting handle is tilted down (the scooping-blade thus tilting upward) after a horizontal forward scooping motion. The handle is arranged along the medial longitudinal-axis of the tool, angling upward at approximately 45-degrees relative to the plane of the scooping-blade, facilitating the special “tilt-loading action” without dragging of one's hand into the cat-litter.
