A trigger mechanism for an animal trap is disclosed, comprising a trigger plate moveable in a vertical direction and provided with at least on e cam surface on its lower face, a retaining pin for preventing release of the trap until triggered, slidable longitudinally thereby to allow release of th e trap, the retaining pin being linked to at least one cam follower, such that downward movement of the trigger plate causes the retaining pin to slide thereby causing release of the trap. The trigger plate and the retaining pin are preferably biassed in an adjustable manner so as to allow a degree of selectivity in the animals which are caught.
