PROBLEM TO BE SOLVED: To easily manage health of a pet by easily recognizing change of the color of special functional granular pieces and the color of urine itself by blending the special functional granular pieces at a prescribed blending ratio, and to suppress unnecessary cost increase.SOLUTION: The granular pieces 1 for a pet toilet are composed of the special functional granular pieces 3 containing an indicator which discolors in contact with urine on the surface, and regular granular pieces 2 without special functions. The special functional granular pieces 3 are blended at the ratio of at least 8 wt.% and less than 35 wt.%, and the regular granular pieces 2 are blended at the ratio of less than 92 wt.% and at least 65 wt.%. The surface of the regular granular pieces 2 is white, and the whiteness of the white granular pieces 2 is at least 57%. With this structure, the special functional granular pieces 3 can be securely interposed in the urination range, and the color of the urine itself absorbed in the white granular pieces 2 can be easily recognized, so that the health of the pet can be easily managed.COPYRIGHT: (C)2012,JPO&INPIT【課題】特殊機能付粒状片を所定の配合比率で混合することにより、特殊機能付粒状片の色の変化及び尿自体の色を確認し易くし、ペットの健康管理を容易にするとともに、余計なコスト増加を抑える。【解決手段】ペット用トイレ粒状片1は、表面に尿との接触により変色する指示薬を含有した特殊機能付粒状片3と特殊機能を有さない通常の粒状片2とからなり、前記特殊機能付粒状片3を8重量%以上35重量%未満、前記通常の粒状片2を92重量%未満65重量%以上の配合比率で混合する。また、前記通常の粒状片2は表面が白色の粒状片とされ、前記白色粒状片2の白色度を57%以上とする。これにより、排尿範囲内に特殊機能付粒状片3を確実に介在されることができるとともに、白色粒状片2に吸収された尿自体の色が識別しやすくなり、ペットの健康管理が容易となる。【選択図】図1
