Which device is required on a leg-hold trap to absorb shock?

A shock absorbing device is specifically designed to mitigate the impact and stress placed on both the captured animal and the trap itself when the animal struggles. This device reduces the sudden jolt that occurs upon capture, which can prevent injury to the animal and maintain the integrity of the trap. Shock absorbing devices are essential in ensuring humane trapping practices, as they help to minimize pain and stress for the animal during capture.

While other options like trap pads and tension devices have their own functions, such as enhancing comfort and security, or ensuring proper tension in the trap mechanism, they do not serve the same purpose in absorbing shock as a dedicated shock absorbing device does. Double chain swivels may assist in providing more freedom of movement for the captured animal but don’t specifically address the shock impact of the trap. Thus, the correct answer emphasizes the essential role of a shock absorbing device in promoting humane trapping practices.
