An animal actuated drinking fountain has an electronic circuit for operating a pump to supply water to an animal. The fountain has a housing with a container for holding the water. A pump receives water from the container and has an upward directed discharge port for creating a fountain of water. A light emitter and light sensor are positioned so a beam of pulsed light is positioned above the surface of the water in the container. When the animal interrupts the beam of pulsed light, electronic circuitry causes the pump to turn on and create a fountain of water for the animal to drink.

We claim: 1. An animal actuated drinking fountain for supplying a liquid to an animal, comprising: a housing having a container for holding the liquid; a pump communicating with said container, said pump having a discharge port for discharging the liquid; a light emitter for emitting a beam of pulsed light; a light sensor for directly receiving said beam of pulsed light emitted by said light emitter; and said light emitter and said light sensor attached to said housing so that said beam of pulsed light is directed over said container; wherein reception of said beam of pulsed light by said light sensor being effective to maintain said pump inoperative; and, interruption of said beam of pulsed light by the animal being effective to turn on said pump. 2. The animal actuated drinking fountain according to claim 1, the liquid having a surface, said animal actuated drinking fountain further including said beam of pulsed light disposed a distance of between about one inch and about four inches above the surface of the liquid. 3. The animal actuated drinking fountain according to claim 1, further including said beam of pulsed light having a duty cycle of 0.1 to 0.00001. 4. The animal actuated drinking fountain according to claim 1, further including said beam of pulsed light having a duty cycle of about 0.001. 5. The animal actuated drinking fountain according to claim 1, further including said beam of pulsed light including pulses having a pulse duration of 1.0 milliseconds to 0.0001 milliseconds, and a pulse period of 100 milliseconds to 1000 milliseconds. 6. The animal actuated drinking fountain according to claim 1, further including said beam of pulsed light including pulses having a pulse duration of about 0.2 milliseconds and a pulse period of about 200 milliseconds. 7. The animal actuated drinking fountain according to claim 1, further including: the liquid having a surface; said beam of pulsed light disposed a distance of between about one inch and about four inches above the surface of the liquid; said beam of pulsed light having a duty cycle of about 0.001; and, said beam of pulsed light including pulses having a pulse duration of about 0.2 milliseconds and a pulse period of about 200 milliseconds. 8. A method for an animal to drink a liquid, comprising: (a) providing a liquid; (b) providing an animal actuated drinking fountain including: a housing having a container for holding said liquid; a pump communicating with said container, said pump having a discharge port for discharging said liquid; a light emitter emitting a beam of pulsed light; a light sensor directly receiving said beam of pulsed light emitted by said light emitter; said light emitter and said light sensor attached to said housing so that said beam of pulsed light is directed over said container; and, wherein, reception of said beam of pulsed light by said light sensor being effective t maintain said pump inoperative; and when said beam of pulsed light is interrupted said pump is turned on; (c) placing said liquid in said container; (d) placing said animal actuated drinking fountain in ambient light; (e) the animal interrupting said beam of pulsed light causing said pump to turn on and discharge said liquid from said discharge port; and, (f) the animal drinking said liquid from said discharge port. 9. The method of claim 8, further including: in step (a), said liquid having a surface; and, in step (b), said beam of pulsed light disposed a distance of between about one inch and about four inches above said surface of said liquid. 10. The method of claim 8, further including in step (b), said beam of pulsed light having a duty cycle of 0.1 to 0.00001. 11. The method of claim 10, further including in step (b), said beam of pulsed light having a duty cycle of about 0.001. 12. The method of claim 8, further including in step (b), said beam of pulsed light including pulses having a pulse duration of 1.0 milliseconds to 0.00001 milliseconds, and a pulse period of 100 milliseconds to 1000 milliseconds. 13. The method of claim 12, further including in step (b), said beam of pulsed light including pulses having a pulse duration of about 0.2 milliseconds and a pulse period of about 200 milliseconds. 14. The method of claim 8, further including in step (b), said animal actuated drinking fountain further including a power supply for providing electrical power to said pump, said light emitter, and said light sensor, said power supply being one of (1) a battery, (2) a solar panel recharging a battery, and (3) an AC to DC converter recharging a battery.
