PROBLEM TO BE SOLVED: To keep a bedding material for pet clean. SOLUTION: A floor board 1 is separable from a side wall 6 and core boards 2 and 7 of the separated side wall 6 and the separated floor board 1 are covered with detachable covers 3 and 8, respectively. The core boards 2 and 7 are formed by covering urethane foams made into each shape with a nylon taffeta. The floor board 1 has the same shape as that of a lower bottom 9 and a size somewhat larger than that of the lower bottom. When the floor board is placed on the lower bottom 9 in the wide wall 6, pressurized from the inside of the side wall 6 and latched by the side wall 6. Both the covers 3 and 8 of the floor board 1 and the side wall 6 are made of a washable cotton cloth. When the bedding material 10 is terribly stained, the floor board 1 is separated from the side wall 6, the covers 3 and 8 are removed from the core boards 2 and 7 and washed so as to always keep the bedding material 10 clean. Since the core boards 2 and 7 are formed by coating urethane foams with the nylon taffeta, the surface is slippery and the covers 3 and 8 are smoothly attached and removed.
