Claim
The agony and terror of trapped animals is excruciating. In the case of the leghold trap, the animal awaits the arrival of the trapper who finally kills it by clubbing or through strangulation (to protect the fur). Many animals, especially nursing mothers, have been known to chew off their legs to escape.
Counter-claim
Since there are few natural predators left in the wild, trappers fulfil an important function in maintaining a natural balance and preventing the population escalation of certain species.
