A rat catching box includes a box body, a lifting platform, and a control assembly. The box body is provided with a trap opening and a recovery opening. The lifting platform is disposed at the bottom of the box body, and a rat catching platform parallel to the lifting platform is disposed above the lifting platform. The control assembly is disposed on the box body, and includes a voltage measurement module, a controller, a high-voltage transformer, and a power grid. The voltage measurement module transmits a triggering signal of the power grid to the controller, and the controller controls the high-voltage transformer to supply power to the power grid. The power grid includes a positive power grid line and a negative power grid line. The negative power grid line in disconnection is divided into three segments connected respectively to a negative electrode of the high-voltage transformer.
