A caged rodent trap assembly catches a rodent by placing bait within a cage to make it harder for the rodent to escape. The assembly includes a platform. A jaw is pivotally coupled to the platform and pivotable between an open position and a closed position. A biasing member is coupled to the jaw and configured to bias the jaw toward a front edge of the platform such that the jaw is forced downwardly against an animal to be caught. A hold-down bar is mechanically coupled to the jaw and configured to retain the jaw in the open position. A trigger plate is positioned above the top surface and configured for receiving bait thereon. The jaw is pivoted onto the animal when pressure is applied to the trigger plate. A cage is coupled to the trigger plate and configured to inhibit the animal's access to the bait.
