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.

Local foxes were not scared by it at all. I could see that they were
aware of the device going off but apart from maybe a jump of a few feet
they carried on regardless.

And no I dont have a gun.

I believe that an effective deterrent is to put some food out laced with
some anti-freeze. Other than that a large store of stones to throw
keeps then on their toes.
