More particularly the invention relates to a unique snare trap design which utilizes a vertically oriented coiled spring which, when triggered, releases vertically to cause constriction of the snare about the leg of the animal in the trap. The vertical arrangement of the coiled spring leads to an upward release of the snare which provides a means to minimize the loss of snared animals while also minimizing the discomfort or injury to the animal and damage to the animal pelt by the recoil spring action. | |
