PROBLEM TO BE SOLVED: To provide a game device for a cat in which the recombination flexibility of a cats riding member where the cat rides thereon and the cats game flexibility are high, and also the strength enabling sufficient support can be obtained even if many cats ride or even if a large-sized cat rides thereon.SOLUTION: A game device for a cat includes a strut group 15 arranged at intervals and using 4-struts 14 extending vertically as a set, a horizontal rack part 16 crossing between the struts 14 and having multi-stages vertically, and a cats riding member 12 inserted between the struts 14 and mounted to the horizontal rack part 16 detachably. Multiple fixing parts for fixing the cats riding member 12 are formed on a virtual circumference around the center point of the strut group 15 of the horizontal rack part 16 in a virtual plane having the horizontal rack part 16 of the same height among inside areas of the strut group 15, and a fixed part coupled with the fixing part is formed at the position corresponding to the fixing part in the cats riding member 12. The fixing part is formed in the symmetrical arrangement capable of being mounted even if the insertion direction of the cats riding member 12 is changed.SELECTED DRAWING: Figure 1【課題】猫が乗る猫乗り部材の組み替え自由度も猫の遊戯自由度も高く、多数の猫が乗っても、また大型の猫が乗っても十分な支持が可能な強度が得られるようにする。【解決手段】間隔をあけて配設されて上下に延びる4本の支柱14を一組とする支柱群15と、支柱14間を横切る上下に複数段の横架部16と、支柱14間に差し込まれて横架部16に着脱自在に取り付けられる猫乗り部材12を備える。支柱群15の内側領域のうち同一高さの横架部16を有する仮想平面における横架部16の、支柱群15の中心点を中心とする仮想円周上に、猫乗り部材12を固定する複数の固定部を形成し、猫乗り部材12における固定部に対応する位置に、固定部と結合する被固定部を形成する。固定部は、猫乗り部材12の差し込み方向を変更しても取り付け可能とする対称配置で形成する。【選択図】図1
