ive been playin around with some snare traps that i made out of whatever i had lyin around the house. im tryin to catch some rabbits out of the feild in my back yard but so far have been unsuccessful. im still tryin to figure out exactly what happens when the animal gets caught. does it have to stick its head in the loop (snare) and pull it tight? do i really even need a tightening loop if im just tryin to catch rabbits or will i have the same results with a smaller loop that doesnt tighten?
