Abstract

A combination of a litter device for use with cats which has a sorbent pad laminate for the collection of animal urine consisting of a bottom sheet layer of moisture impermeable material in contact with the base and walls of the litter device, an intermediate sorbent layer of material having a high absorbency capacity for urine, a top claw resistant screen and securing device. The securing device removably affixes the sorbent pad laminate to the litter device, thereby preventing the relative movement between the sorbent pad and the litter device which can be caused by the clawing action of an animal.
