A drinking fountain is designed for use by a pet and is formed of water container and a spout structure. The spout structure includes a spout tube, a hollow seat, and a ball. The spout tube is in communication with the water container and is provided in the inner wall with two locating projections between which the hollow seat is located. The hollow seat is provided in the inner wall with an annular stop edge. The ball is movably disposed in the seat such that the ball is stopped and supported by the annular stop edge, and that the ball is partially exposed through the bottom end of the spout tube so as to enable the ball to be licked by the pet, thereby resulting in the passage of water through the bottom end of the spout tube.
