<；P>；PROBLEM TO BE SOLVED: To provide an excrement container for small animals, which can easily be attached to or detached from a cage and can thereby improve the workability of the attaching or detaching works to the cage. <；P>；SOLUTION: A setting structure 70 for detachably fixing a container body 20 to the vertical lattice bars 92 of the cage 90 has an operation piece 731 placed on the inside of an upper container 30 and a nipping piece 732 placed on the outside of the upper container 30. The length dimension of the nipping piece 732 is set to a larger dimension than a distance between the vertical lattice bars 92, and the width dimension is set to a smaller dimension than the distance between the vertical lattice bars 92. The setting structure 70 is formed in a state capable of being switched between a fixed posture for nipping the vertical lattice bars 92 and a released posture capable of being inserted into a space between nipping members by a rotation operation with the operation piece 731. <；P>；COPYRIGHT: (C)2010,JPO&INPIT
