Abstract

A self-mobile cat toy capable of simulating intermittent life includes a rodent-like shell partially or wholly containing an electrical power source mechanically and electrically connected to motor-powered wheels or a tread mechanism for moving along the ground. The power circuit includes an orientation-dependent switch which is closed or open depending on its orientation, so that when played with by a cat, the toy will cease to move in certain orientations and begin to move when pawed into other orientations. In another embodiment the powered wheels or tread are replaced by a vibrating mechanism. In yet other embodiments the cat toy is externally controlled by the pet owner, through either a long cable with a switch at the end or through a radio or ultrasonic transmitter-receiver system.

Claims

1. A cat toy simulating intermittent life, comprising:

a shell simulating the exterior of a small nonhuman animal defining an interior volume; and

means for intermittenly moving substantially inside said volume and attached to said shell for intermittently moving said toy along the ground, said means for intermittenly moving operable by direct mechanical actions of a cat playing with said cat toy, said actions involving actual physical contact of said cat with said toy to alter a spatial orientation of said toy.

2. The cat toy of claim 1 wherein said means for intermittenly moving comprises:

motor means for providing mechanical output energy in response to electrical input energy;

a tread-like mechanism attached to said shell including a continuous belt operatively connected to said motor means;

power means for powering said motor means; and

switching means for intermittent connection of said power means to said motor means.

3. The cat toy of claim 1 wherein said means for intermittenly moving comprises:

at least one wheel extending beyond said shell;

driving means for driving said at least one wheel;

power means for powering said driving means; and

switching means for intermittent connection of said power means to said driving means.

4. The cat toy of claim 1 further comprising squeaking means for emitting squeaking sounds in synchrony with an activation of said power means.

5. The cat toy of claim 2 wherein said switching means comprises at least one orientation-sensitive switch, a first of said at least one switch being connected in series with said motor means and said power means, and any said switches in excess of said first switch being connected in parallel with said one switch and with each other.

6. The cat toy of claim 5 wherein said at least one orientation-sensitive switch comprises a mercury switch.

7. The cat toy of claim 2 wherein said switching means comprises a mercury switch.

8. The cat toy of claim 2 further comprising sound-producing means for simulating the squeak of a mouse.

9. The cat toy of claim 2 wherein said shell comprises a soft material simulating the exterior of a small animal.

10. A cat toy simulating intermittent life, comprising:

small animal means for simulating the shape and appearance of a small nonhuman animal;

means for moving in said small animal means for moving said small animal means along the ground; and

an orientation-dependent switch in said small animal means, operatively connected to said means for moving for turning said means for moving on or off depending upon an orientation of said small animal means, said switch operable by direct mechanical actions of a cat playing with said cat toy, said actions involving actual physical contact of said cat with said toy to alter a spatial orientation of said toy.

11. The cat toy of claim 10 wherein said means for moving comprises a small electrical motor electrically connected serially to a battery source and to said switch and mechanically connected to at least one wheel on an underside of said small animal means.

12. The cat toy of claim 11 wherein said orientation-dependent switch comprises a mercury switch oriented so as to conduct electricity when said small animal means is in an upright position with said at least one wheel in contact with the ground but not to conduct when said small animal means is not so oriented.

13. The cat toy of claim 10 wherein said means for moving comprises a small electrical motor electrically connected serially to a battery source and to said switch and mechanically connected to a continuous tank-like tread on said small animal means.

14. The cat toy of claim 13 wherein said orientation-dependent switch comprises a mercury switch oriented so as to conduct electricity when said small animal means is in an orientation with said tread in contact with the ground but not to conduct when said small animal means is not so oriented.

15. The cat toy of claim 10 wherein said orientation-dependent switch comprises a plurality of mercury switches disposed in a plurality of different positions so as to conduct electricity when said small animal means is oriented in certain positions but not to conduct when said small animal means is not so oriented.
