A pet watering device for use in a vehicle that has a basin with sidewalls, a bottom and a porous member mounted over the bottom, forming an upper and a lower chamber. The porous member permits the passage of water from the upper to the lower chamber but preferably does not permit the reverse flow of water there through. Water is pumped from the lower to the upper chamber, the amount being substantially equal to the water passing through the porous member and sufficient to maintain the presence of a thin, constant layer of water over the porous member. The device is securely mounted in the vehicle. When the watering device is jostled by the moving vehicle water does not pass from the lower to the upper chamber through the porous member and only a small amount, if any, of water slops out over the upper rim of the basin. |

1. A pet watering device comprising:
a. a first basin for holding water that has first basin peripheral sidewalls extending upward from a first basin bottom wall, the first basin peripheral sidewalls having an interior surface, exterior surface and upper rim; b. a porous member having a plurality of holes there through, the porous member mounted to the interior of the first basin peripheral sidewalls over the bottom wall to form an upper chamber and lower chamber in the first basin,
i. wherein the plurality of holes in the porous member permit the passage of a first amount of water over a period of time from the upper chamber to the lower, andii. wherein the upper chamber is open to permit the pet to drink water therefrom; c. an electrical pump means for pumping a second amount of water over a period of time from the lower chamber to the upper chamber,
i. wherein the second amount of water over a period of time that is pumped from the upper chamber to the lower chamber is about no greater than the first amount of water over a period of time passing through the porous member from the upper chamber to the lower chamber, sufficient to maintain the presence of about a constant layer of water over the porous member and below the upper rim; d. a mounting means for securely mounting the pet watering device in a vehicle such that the porous member is on a level plane. |
