Abstract
The combination of a sorbent pad laminate and a litter device for the collection of animal urine having a bottom sheet layer of moisture impermeable material, overlying the base of the device, an intermediate sorbent layer of material having a high sorbency capacity for urine and a top claw resistant screen. The bottom sheet layer and top screen are bonded to each other along at least a substantial portion of the periphery of the screen. The screen is a urine permeable, flexible member of nonwoven material which is substantially inert to urine, formed of strands randomly fused together at their intersections and having sufficient tear strength to withstand the clawing action of a cat.
