The present invention relates to an animal capture system (10). It is described to move (210) a door of a cage to an open position. When the door is in an open position an opening of the cage is suitable for the entry into the cage of an animal that is the size of a coypu. When the door is in a closed position, the door blocks the opening of the cage to prevent exit of the animal from the cage. An animal food is contained (220) within the cage. A switch system comprises a door closing mechanism； and wherein the switch system is configured to close the door when the animal has entered the cage. A transmitter is attached (230) to the cage or placed securely in proximity to the cage. A connector is connected (240) to the door. The connector is connected (250) to the transmitter in a releasable manner via first releasable connection means. When the door is in the open position the connector is connected to the transmitter and connected to the door, wherein connection of the connector to the transmitter comprises attachment of the first releasable connection means to the transmitter. When the door moves from the open position to the closed position the connector disconnects from the transmitter, wherein disconnection of the connector from the transmitter comprises detachment of the first releasable connection means from the transmitter. A signal is transmitted (260) by the transmitter to indicate that the cage is occupied when the first releasable connection means detaches from the transmitter.
