The invention is a snare threaded through a compression spring delivered to the animal via a two-jaw animal trap. The snare consists of steel or other resilient cable, a snare lock and other wire rope devices sufficient for making a snare, flexible tube, a spring retention washer, “J” clip, and a compression spring. The snare assembly is threaded through a piece of rigid tubing which serves to direct the energy of the compression spring. The compression spring causes the snare to lock upon the animal when the trap is activated, and the flexible tube reduces the possibility of rope burns or other injury to the animal.
