Green snakes, from the southeastern United States, adapt well to captivity if provided with a tropical jungle-type cage. These snakes get along well with other creatures (except insects, which they will eat), and are most comfortable in woodland settings. Mist the cage and plants daily with a water bottle, as some green snakes will only drink water droplets off branches. Provide a small margarine tub-sized container, filled with damp moss. This makes a nice moist retreat for this humidity-loving snake.
