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!


There was a cat that used to **** in my porch, I put down some cat
repellent pellets from B&Q - it used them as cat litter.

I borrowed a terrier off a friend.
