Abstract: An animal extraction gate which can be fitted in any of multiple vent openings in a foundation wall or siding of an elevated structure to enable exit of an animal or animals from beneath the structure through the animal extraction gate while preventing re-entry of the animal or animals through the gate and beneath the structure. The animal extraction gate includes a gate frame for attachment to the vent and having a gate door pivotally mounted on the gate frame. The gate door is movable between a closed position wherein the gate door closes the frame opening and an open position wherein the gate door opens the frame opening. A bias mechanism biases the gate door in the closed position.
