Abstract
To provide a movable hood which can be opened and closed smoothly even though a distance between the movable hood and a fixed hood is reduced. An animal litter box 1 comprises an evacuation container 2; and a hood 3, the hood 3 having a fixed hood 31, a movable hood 32, and a pair of connecting portions, wherein the movable hood 32 is configured to be moved rotatably outside or inside the fixed hood 31 in the state that an end edge is proximal to the fixed hood 31 with maintaining a prescribed distance, and wherein at least one of the fixed hood 31 and the movable hood 32 is provided with a convex restricting portion 6 which prevents a distance between an end edge on at least the one end of the movable hood 32 and the fixed hood 31 from being less than the prescribed distance.
