To provide an animal toilet keeping the animal toilet and the periphery thereof clean and suppressing generation of urine smell.SOLUTION: A duckboard includes multiple rectangular through-holes 36 formed of longitudinal members 34 and cross members 35. Lower ends of the longitudinal members 34 are downward-projecting inverted arch parts 37 repetitively continuing in the longitudinal direction, and the lowest ends 37a thereof are located immediately beneath the cross members 35, while the uppermost ends 37b thereof are located at central positions between the adjacent cross members 35 and located on the upper side of the lowest ends 35d of the cross members 35. Urine forms a liquid thin film spread on the whole surface of each through-hole 36, then the thin film is lowered by the force of gravity, is divided into two vertically by passing through the uppermost end 37b of the inverted arch part 37, then flows from the lateral surface of each longitudinal member 34 along the inverted arch part 37 of the longitudinal member 34, is gathered at the lowest end 37a, and dropped as a large liquid droplet.SELECTED DRAWING: Figure 7【課題】動物用トイレとその周囲を清潔に保ち、尿臭の発生を抑制する動物用トイレを提供する。【解決手段】簀子は、縦材34と横材35とによる多数の長方形の透孔36を有する。縦材34の下端は、縦方向に繰返して連続する下に凸の逆アーチ部37であり、その最下端37aは、横材35の直下方にあり、その最上端37bは、隣接する横材35間の中央位置で、横材35の最下端35dよりも上方にある。尿は、透孔36の全面に拡がった液体の薄膜を形成し、次に、その薄膜が重力で下降して逆アーチ部37の最上端37bを経ることによって、縦に2つに分断され、その後、縦材34の外側面から、縦材34の逆アーチ部37に沿って流れ、最下端37aに集まって大きな液滴となって落下する。【選択図】図7
