I've had complete success with a PIR triggered ultrasonic scarer. I
modified it to run from a 6v dc wallwart instead of the 4 aa cells
that it was designed to use and all sealed up with neutral cure
silicone sealant.
It is located at one corner of a roughly 7m square grassed area with
flower beds on 3 sides and no sign to any cats deposits since I
installed it a couple of years back.
The garden is completely open on one side and used to be a regular
short cut for local felines, ****ting as they went but no more.

Even if you had to run several for a larger area, it would be much
cheaper than fencing.




I've got one of those with regular piles of cat **** in front of it!

What is that stuff called that you put into the cooling system of a car?
The stuff that prevents the coolant freezing up?

Antifreeze. And the next time you use it, the neighbours will know
it was you now that Adam has told them about what you get up to.
