A trap attachment for a soup can is an apparatus that is inserted into a soup can or any kind of container in order to create an animal trap. The apparatus is primarily used to catch raccoons by their paw. The apparatus includes a face plate, a trap hole, a hollow body, a torsion spring, a trap door, and a trigger. The hollow body is the structural component of the apparatus and is inserted into the soup can. The face plate prevents the apparatus from being inserted too far into the soup can. The trap hole allows an animal's paw to enter the hollow body through the face plate. The trigger allows the animal's paw to activate the trap door, which closes off the trap hole and pins the animal's paw. The torsion spring forces the trap door to close when the trigger is tripped by the animal's paw.
