Cardboard container with litter pad
First Claim
1. The combination of a self supporting structure and sorbent pad laminate and litter means for the collection of animal urine wherein said self supporting structure is made of a disposable material and has a base and walls;
- said sorbent pad laminate and litter means includinga. a bottom sheet layer of moisture impermeable material, said sheet layer being in contact with said base and walls;
b. an intermediate sorbent layer of material having a high absorbency capacity for urine and a high surface area for evaporation of said urine;
c. a top claw resistant screen means, said screen means being a urine permeable, flexible member of material which is substantially inert to urine, formed of strands bonded at their intersections and having sufficient tear strength to withstand the clawing action of a cat and sufficiently small hole size to protect said sorbent layer and said sheet layer of moisture impermeable material from being torn by animal claws without inhibiting evaporation, said bottom sheet layer and said top claw resistant screen means being bonded to each other along at least a substantial portion of the screens periphery; and
d. litter granules.

Abstract
The combination of a disposable self supporting structure, sorbent pad laminate and litter for the collection of animal urine. The self supporting structure has a base and wall. The sorbent pad laminate includes a moisture impermeable bottom sheet layer in contact with the base and walls, an intermediate sorbent layer of material having a high absorbency capacity for urine, a top claw resistant screen and litter granules. The screen is a urine permeable, flexible member of material which is substantially inert to urine. The screen is formed of strands which are bonded at their intersections and have sufficient tear strength to withstand the clawing action of a cat. The screen must also have sufficiently small hole size to protect the sorbent layer and sheet layer of moisture impermeable material from being torn by animal claws. The bottom sheet layer and top screen are bonded to each other along at least a substantial portion of the screen'"'"'s periphery. The self supporting structures are manufactured from disposable materials and can be used with the aforenoted sorbent pad laminate or a modified sorbent pad. The modified sorbent pad includes the bottom sorbent layer and screen which have been affixed to the self supporting structure. The self supporting structure in this embodiment must be coated with or manufactured from a moisture impermeable material.
