The animal trap stabilizer is adapted for use in bedding coil spring or long spring traps. The animal trap stabilizer is a structure formed in the shape of a rectangular shell that provides a non-compressible surface upon which the coil spring or long spring trap can be set. The animal trap stabilizer has formed in the surface a recessed structure that is shaped to allow the coil spring or long spring trap to be placed within the animal trap stabilizer such that the coil spring or long spring trap will be flush to the surface of the animal trap stabilizers. The animal trap stabilizer further comprises a mounting platform and a recessed structure.
