PROBLEM TO BE SOLVED: To provide a drain-board which can drop materials adhered to legs.SOLUTION: The stepping surface 302 of a drain-board 2, on which a cat 312 steps and passes, is formed into a curved shape which is difficult to walk through. Thus, a cat ends up walking on the stepping surface 302 of the drain-board 2, while straddling the legs 322, 322. The soles 451, 451 of the legs are deformed, to make the spaces between the muscle balls of the soles open, and adhered materials, such as, sand 72, ..., for pets nipped between the muscle balls can be dropped positively. As a result, the residues of the adhered materials between the muscle balls of the soles can be reduced, and the scattering of the adhered materials on the outside of a toilet for a pet 1 can be prevented.COPYRIGHT: (C)2009,JPO&INPIT【課題】足に付着した付着物を落とすことができる簀の子を提供する。【解決手段】猫312が踏んで通過する簀の子2の踏み面302を曲面状に形成し、歩き難い形状に形成されている。このため、足322,322を踏ん張って歩くこととなり、足裏451,451面が変形することで肉球間の隙間を開き、肉球間に挟まったペット用砂72,・・・等などの付着物を積極的に落下させることができる。これにより、足裏の肉球の間の付着物の残存量を少なくすることができ、ペット用トイレ1外部への付着物の散乱を防止することができる。【選択図】図6
