 In a study of foxes in the UK, researchers were unintentionally snaring brown hares about as frequently as the intended foxes until they improved their methods, using larger wire with rabbit stops to eliminate the unwanted catch of the brown hares.Any type of trap—whether it be a foothold/leghold, conibear, or snare/cable restraint—can get an unwanted catch.Both endangered species and domestic pets have been injured or killed by illegally set traps.
