Thinking about getting a cat scarer, the ones that emit a sound inaudible
to us, but which cats can hear.
Have any of you had one? Do they work?

No they don't work. I had one with a PIR sensor and various sound
settings. Humans, depending on their age, can hear them starting up at
the beginning of the ultrasonic sound burst. Initially the local cats
were scared but within a week they got used to it and reverted back to
their old patterns. Even moving the device around a lot had no effect.

I tried one rather similar to the £29.99 version, and the cats
and squirrels were completely unaffected. However my partner's
rather younger ears were sufficiently sensitive to find it
seriously irritating, so it didn't stay in use very long.
