To provide a cage for catching a wild boar or the like and enabling the catching rate of the wild boar which invaded in search of bait placed in the cage to be heightened.

Doors 1a and 1b are installed on respective frontal and back sides so as for a wild boar not to hold wariness when invading a cage in search of bait. Both doors 1a and 1b are suspended by wires 5a and 5b and the entrance of the cage is open. Holding parts 13a and 13b formed at the respective ends of the wires 5a and 5b are engaged with a holding tool 12 fixed on the cage body and the tool 12 is set in such a way that when a string 17 tensively disposed in the neighborhood of the bottom of the cage is caught the tool is released and both doors 1a and 1b simultaneously drop.
