Abstract: An animal trap includes a transparent lampshade-shaped cup slidably held on a vertical supporting pipe standing on a base plate, which cup is normally hanged on an upper portion of the supporting pipe by a biasing lever pivotally secured on a pair of fixed levers as locked by a horizontal bar secured with a bait rope having a bait mounted on a lower end of the rope, whereby upon a taking of the bait by an animal, the horizontal bar as clamped between the fixed levers and the biasing lever will be released to unlock the biasing lever without hanging the cup, thereby dropping the cup for catching the animal.
