ABSTRACT:
A fanciful animal (12) which emits a purring sound when petted. A sensor, comprising an enclosure of a fanciful animal (18), pressure transducer (14) and cushion material (16) is arranged so as to permit at least a portion of said cushioning material to move freely over said pressure transducer when said enclosure is rubbed, producing an output signal of sufficient magnitude to be detected by an electronics assembly (20). The electronics assembly produces a waveform of predetermined form which when applied to a speaker (SP1) simulates a purr.
