Snare traps are used widely in the UK and other countries for predator control. Welfare science consistently identifies snaring as a high-suffering capture method in need of radical reform.
Snare trapping causes suffering that is difficult to justify given the availability of alternatives. An animal caught in a snare — whether target or non-target — experiences acute fear and pain from the entrapment, and then typically endures prolonged distress during the period before the snare is checked. The suffering of non-target animals — a fox caught in a rabbit snare, a domestic cat caught in any snare — is particularly indefensible. Even target animals endure restraint stress, physical injury from entanglement, and the fear of an imminent, unfamiliar threat. The welfare case for snare abolition is strong; the case for continuation rests on pest control practicality and game management convention rather than welfare grounds.
