A mouse chamber, comprising a mouse wetting device (1), a mouse guiding channel (2), a paper wet breakage device (3), a water tank (4) and a water tank cover (5). The mouse wetting device (1) is made up of a water trough (6) and wetting water (7) in the water trough. The paper wet breakage device (3) is made up of a front paper clip (8), a rear paper clip (9) and trap paper (10), the trap paper (10) is provided with a plurality of breakage holes (12), and a paper weak spot (11) is provided between adjacent breakage holes (12). The paper weak spots (11) are located at an exit position of the mouse guiding channel (2). The front paper clip (8) is arranged at a left upper portion (13) of the water tank (4), the rear paper clip (9) is arranged at a right upper portion (14) of the water tank (4), the front paper clip (8) clamps an edge of a left wet breakage paper strip (15) of the trap paper (10), and the rear paper clip (9) clamps an edge of a right paper edge (16) of the trap paper (10). The mouse guiding channel (2) is located between the mouse wetting device (1) and the paper wet breakage device (3). When the mouse chamber is in use, water is brought by a mouse from the water trough to the trap paper, the paper weak spots of the trap paper become wet and break, the mouse falls into the water tank, and the mouse is caught.Linvention concerne une chambre à souris, comprenant un dispositif de mouillage de souris (1), un canal de guidage de souris (2), un dispositif de rupture de papier humide (3) un réservoir deau (4) et un couvercle de réservoir deau (5).
