The invention relates to a litter bowl, which is composed of three identical basins, the upper, the middle and the lower. The upper basin is mainly composed of a sand leakage hole at the bottom and a 30 degree rotation fixed buckle groove at the side. The middle basin structure and the lower basin structure system are the same as the upper basin. When the three basins are overlapped, the 30 degree rotation and fixed buckle groove on the side shall prevail, forming a 30 degree staggered overlap, so that the sand leakage holes at the bottom of the basin can be effectively covered by the way of cross overlap to become a solid basin bottom with the bottom close and no sand leakage.When cleaning the litter, hold the upper basin, lift it up and shake it gently to drain the clean litter onto the middle basin, and after pouring out the dirty litter and excrement in the upper basin, buckle the raised upper basin to the lower basin according to the above-mentioned method of 30 degree staggering and overlapping, so that the above-mentioned method of repeatedly lifting the upper basin and buttoning it to the lower basin can achieve the function of effectively filtering the litter.本新型創作係有關一種貓砂過濾裝置(Litter Bowl)，包括上、中、下三個相同盆子所構成，該上盆部分主要有底部漏砂孔洞及側邊30度旋轉固定扣槽所組成。中盆構造以及下盆構造係與上盆相同，三盆相疊時由側邊上30度旋轉固定扣槽為準，成30度錯開交疊，使得盆底的漏砂孔洞可以有效的被交叉相疊的方式遮蔽成為底部密合不會漏砂的實心盆底。在清理貓砂時，握住上盆，往上提並輕搖的動作將乾淨的貓砂漏至中盆上，倒掉上盆中的髒貓砂及排泄物後，將已經提起的上盆照上述成30度錯開交疊的方式扣至下盆，如此重複提起上述上盆扣至下盆的方式即可達到有效過濾貓砂的功能。
