A hinged trap floor is located in the platform and is moveable between a horizontal closed position and a downwardly inclined open position for causing animals to fall into a holding pen. A plurality of feeder stations are positioned adjacent to the trap floor. The feeder stations each have feeder lids that can be raised by animals to access feed contained in feeder troughs.

A scent roller is also positioned adjacent to the trap floor and is connected to the trigger mechanism by a linkage that causes the trigger mechanism to be tripped when the scent roller is lifted.
