While quick-killing traps are still usually preferable, from a humane perspective (because no wild animal wants to be restrained), live-holding systems are still required for some larger predators (that are too strong or cautious to be taken in killing sets), or when conservation authorities need to radio-collar or relocate animals. The fact that modern foothold traps are used by wildlife biologists to capture and release coyotes, wolves, lynx and other animals unharmed, is the clearest indication that these traps are not the diabolical devices that activists would have us believe.
