An excrement-treating material includes a water-absorbing core part, and a surface layer. The core part is formed by wet-kneading and compression-granulating a compounding material containing a paper powder and organic or inorganic fine pieces. Dents and/or protrusions are formed on the surface of the core part by deformation by the kneading or compression of the fine pieces or peeling-off of the fine pieces from the paper powder upon release of compression. The surface of the core part is discontinuously colored by utilizing the dents and/or protrusions, and covered with the surface layer. The colored parts of the surface of the core part are exposed through the surface layer during absorption of excreted urine, while the non-colored part of the surface of the core part is stained by the color of the excreted urine, and the color of the excreted urine is exposed through the surface layer.

An excrement-treating material has a core part, and a surface layer bonded to the core part by utilizing the adhesion ability of a water-absorbable polymer in the surface layer without using an adhesive. The excrement-treating material suitably exerts the water absorbability and water transport ability inherent to the surface layer. The excrement-treating material is constituted by incorporating pulverized water-absorbable polymer particles of 20 &#x3bc;m to 50 &#x3bc;m, and adding water to the surface of the core part after granulation to noncontinuously form a highly-wet part; reacting a water content in the highly-wet part and the pulverized water-absorbable polymer to noncontinuously form an adhering part; and bonding the surface layer to the core part through the adhering part. Upon absorption of excreted urine, permeation of the urine into the core part is accelerated in a part other than the adhering part.

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 (') is coated by a slow water-semipermeable coating (); and because of the slow water-semipermeable coating (), urine is prompted to pass between the water-absorbing grains, and residual urine () sweating the surface of the water-semipermeable coating () is gradually absorbed into the water-absorbing grains (&#x2032;) through the water-semipermeable coating ().

An extrusion type compressive granulating apparatus is configured to produce granular excreta treating material that has an absorbing property and is formed by extruding and granulating a raw material via granulating holes formed in a table of the apparatus. A space rib is provided at a lower surface of the die table so as to form a gap below the granulating holes. A cutting blade is provided below the gap. The granulating holes each form a compression zone for compressing the raw material, and the gap forms a non-compression zone in which the compressed material swells before being cut by the cutting blade at the outlet of the non-compression zone.
