Code: L515The Only Cat deterrent tested and recommended by the RSPB Does it work? Can you prove it? Will I get value for money? The answer to these questions is YES!! This product has recently and successfully completed a two-year scientific trial conducted by the RSPB to determine its deterrent effect on cats in residential gardens. The result will be published in the Animal Behavioural Science journal for peer review. And the Results? IT WORKS!! The ultimate cat deterrent. Simplicity itself - clip in a single 9v battery or use our mains adaptor kit (Code: L515/M). Only the finest quality components are used to produce Catwatch. After many years research and development it was established that maximum performance could only be achieved by using the highest specification equipment in four critical areas - namely, the power source, LED detector, microchips and speaker. And it is this attention to detail that has made Catwatch not only the original and still the best electronic cat deterrent available but also the top selling model in Britain today. Since 1994 Catwatch has been used by the R.S.P.B. with great success to protect their bird sanctuaries with cat problems.
