## Abstract

An animal amusement device wherein a radio transmitter of limited range is carried by the animal.

Upon the animal moving to within a short distance of the ball, the ball will become randomly movable by being activated by the radio signal mounted within the collar of the animal.

## Claims

### Claim 1

Animal attraction apparatus comprising:
motor means for operating only when actuated;
transmitter means for transmitting a signal;
receiver means having an output coupled in actuation relationship to said motor means, said receiver means being for receiving said signal and, when said signal as received is of predetermined power, for causing actuation of said motor means;
attachment means for carrying said transmitter means and for mounting on a domesticated animal of the predator type; and
simulated prey means which is normally unmoving and which, when in motion, tends to attract such animal, said prey means being for carrying said motor means and coupled to said motor means so that said motor means, when actuated, operates to cause said prey means to move;
said transmitter means and receiver means having a signal transmitting and receiving power relationship such that, when said transmitter means is carried by such animal to within a predetermined distance of said prey means, said receiver means actuates said motor means to cause said prey means to move.

### Claim 2 (depends on 1)

The animal attraction apparatus as defined in claim 1 wherein:
said attachment means comprises a collar which is adapted to be worn around the neck of the animal.
