An animal trap system that improves the reliability of a pre-existing animal trap is provided. The animal trap system may include a thin membrane forming an opening, wherein the opening is dimensioned to at least partially circumscribe a trigger mechanism of the pre-existing animal trap, while a remaining portion of the trap mat overlays a substantial portion of a supporting surface and/or base of the pre-existing animal trap where the animal may be dispose when setting off the trigger mechanism. The underlying surface of the trap mat may have a relatively low friction coefficient so as to cause a fleeing animal to slide and or slip along the supporting surface and/or base.
