A birdcage watering device is provided with a no-spill valve and method of attachment. The watering device comprises a valve attached to a water chamber comprising an extended leg such that when the watering device is completely assembled the valve may be displaced to fill trough. Particularly, the extended leg of the valve produces an angled opening to permit flow of water from the water chamber without clogging or getting "stuck" in the valve opening. The water chamber is easily removed for refilling and the valve is designed to prevent the spilling of water during the process. A method of attachment is also described that allows the device to be on the outside of the birdcage while being secured from the inside of the cage, thus allowing for easy refilling of the water chamber of the device.
