an open container that is filled with material that absorbs liquid and is used as a toilet for cats

I put the litter tray in the corner of the room with a screen in front of it. 我把猫砂盆放在房间的角落里，前面有一个屏风。

If a cat seems unable to use the litter tray, it should be taken to the vet without delay. 如果猫咪似乎不能使用猫砂盆，应该立即带它去看兽医。
