An animal trap for catching mice has a box-shaped housing with foundation housing and attached to it is the cover housing, capable of swiveling. Arranged in the interior of the housing, there is a triggering system designed like a seesaw with a stepping platform. The cover housing is locked in the open position with the help of mechanical restraint devices. A locking mechanism resting in the cover housing has an unlocking button for restoring the open position, as well as an operating button for the user to transfer the cover housing into closed position.
