Gives a pulse of ultrasonic wave at a frequency range of 18k.hertz to
24 k.hertz, the lower part of the spectrum 'just' being audible.

18 - 24 kHz doesn't really strike me as 'ultrasonic' as I'd suspect that
many people can hear a fair part of that range. (Although not me anymore.
My hearing is now cut off by about 14 kHz.)

One neighbour had one; just audible like tinnitus. However never seemed
to bother another neighbours cats near the source. May be just
coincidence but something has struck a cord (sorry), since the noise
has stopped I have noticed a much bigger variety of birds in garden.

So what *is* the best way to get rid of cats?


Heard an interesting item on radio recently. With the replacement of binbags by
wheelie bins, urban foxes are unable to find enough food from domestic rubbish.
Instead, some of the foxes are now catching and eating cats......
