The present invention provides a floor material for pet animal urination, which has an effect to allow urine to pass through by suppressing speed and amount of urine absorption, as well as an effect of low water absorbency allowing to gradually absorb residual urine sweating the grain surface, which also has good shape retentivity so as not to be collapsed even if urine is absorbed, and thus which is highly suitable as a floor material for pet animal urination.There is provided a floor material for pet animal urination, wherein a surface of each of water-absorbing grains (1) is coated by a slow water-semipermeable coating (6) and because of the slow water-semipermeable coating (6), urine is prompted to pass between the water-absorbing grains, and residual urine (8) sweating the surface of the water-semipermeable coating (6) is gradually absorbed into the water-absorbing grains (1) through the water-semipermeable coating (6).
