Claim Text:
1. A floor material for pet animal urination used in a pet animal litter system having a urine-absorbing material for absorbing urination, which floor material comprises urine-absorbing granular particles formed by aggregating a urine-absorbing material, for prompting a pet animal to excrete arranged in an upper tier and an absorptive material in a lower tier for absorbing urine passed through the floor material, wherein after the particles are formed by aggregating the urine-absorbing material a water-semipermeable coating is applied to coat the entire surface of each of the granular particles which water-semipermeable coating slows urination absorbing speed as compared to urination absorbing speed of non-coated granular particles of the urine-absorbing granular particles; the water-semipermeable coating contains a sizing agent; wherein the water-semipermeable coating containing the sizing agent promotes the passage of urine between the urine-absorbing granular particles, and allows residual urine wetting the surface of the water-semipermeable coating to be gradually absorbed into the urine-absorbing granular particles through the water-semipermeable coating, and wherein the pet litter system includes a porous plate that supports the floor material so that the floor material is above and spaced apart from the urine-absorbing material with an open space between the floor material and the urine-absorbing material, the porous plate having a plurality of openings therein through which urine passes and drops onto the urine-absorbing material.
