PROBLEM TO BE SOLVED: To provide an absorption tool and a sheet enabling the confirmation of absorbed liquid by color. SOLUTION: The sheet 1 for a pet animal is composed of a white translucent or colorless transparent surface sheet 2, a back sheet 3 and an absorption sheet 4. The absorption sheet 4 is placed between the surface sheet 2 and the back sheet 3, and the liquid penetrated through the surface sheet 2 is absorbed by the absorption sheet 4. The inside of the pet sheet 1 is not masked and the mixing of the color of the liquid with the color of the constitution elements of the pet sheet 1 to generate another color is prevented in the case of observing the color of the absorbed liquid from outside of the pet sheet 1. When the liquid contains a solid component, the solid component is separated by the surface sheet 2 and the surface part of the absorption sheet 4 to enable the absorption of the liquid in the absorption sheet 4. The color of the liquid and that of the solid component are separately recognized while preventing the interference of the colors. COPYRIGHT: (C)2005,JPO&NCIPI
