An animal trap (100) in the shape of an expandable collapsible prismoidal box is made out of cardboard and has a stiff square top (30) and bottom (31) and four side walls (2, 5, 6, 16) which are foldable to the outside along central folding lines by pressure onto the top. Each side wall has an inwardly extending tongue and at least two tongues on opposite side walls which are connected by elastic bands or a contracting spring (17) which pull the walls back from their folded positions into a partially planar state as soon as the pressure on the top is released. The square tops are connected by a baited string (14) which holds the trap in its partial state thus creating corner openings through which an animal may gain access to the trap.
