Abstract: An animal trap is disclosed which includes a substantially planar baseboard. A first generally U-shaped jaw member is provided which has at least one free end thereof pivotally mounted to the baseboard about a pivot axis substantially parallel to the plane of the baseboard surface. A second generally U-shaped jaw member is provided which has at least one free end thereof pivotally mounted to the baseboard about the pivot axis. A spring is provided which cooperates between the baseboard and the first and second jaw members for urging the jaw members from the set position to the sprung position in which cross-bar section of the first jaw member engages the baseboard on one side of the pivot axis. The U-shaped second jaw member is larger in size than the first U-shaped jaw member and includes a bag extending between the parallel legs thereof. When the trap is in the set position the outer surface of the bag is adjacent to the baseboard and the inner surface of the bag is adjacent the first jaw member.
