ONEDOWN is a humane rat trap. The trap rests precariously in a horizontal position on a circular foot. Bait inside would lure the rat into the trap, a metal insert in the base coupled with the weight of the rat will tip the trap and bring it to a vertical position indicating that a rat has been trapped. Then the rat can be released instead of killed.
