When you spot the offender give it a couple of shots. They take off quick smart. Then being cats they clean themselves and the taste of vinegar makes them dislike getting sprayed.
this is from a vet so is safe. Doesnt take long to work either.
Then every couple of days give the fence line or whatever the cat uses to enter your property a spray and hey presto, force field for Tiddles!!!

Sorry about your cat Peter.
I'm gonna call shennanigans on this one.
Sounds like an old wives tale to me; how the heck do you get close enough to spray the offending cat?
They take off like a rocket when you see them in your yard, unless you've been friendly to them previously which means you've encouraged them coming ino your yard, so unless you're as fast as the Flash, you ain't gonna spray one.
Damn I had a good laugh this morning when I went to work; there's been a grey cat lately spraying our front door, and it bloody stinks, so this morning I'm reversing out the driveway and I see the offending cat walking back home from wherever he's been, he has to cross our yard to get home.
So I'm half out of the driveway, I stop, he stops, and we look at each other for a few seconds, both of us working out our game plans.
He thinks he can make it past me and I know if I get out of the car to chase him, he will, so I put the car in drive and put my foot down, heading him off at the pass so to speak.
He craps it and turns tail, but I'm still in between him and his destination/safe place.
As he tries to run around behind the car I floor it and swing the car around and chase that little bastard down the street, man can that cat run!
I chase him down the street for maybe 10-15m till he decides to veer off the road and onto the opposite verge, but keeps running further for good measure.
Laughing like a maniac I decide I've had my funnest morning for ages and watch him sitting there looking at me as I drive off, I can imagine him thinking 'WTF just happened??'
I'd never have the heart to run him over, but damn it was so good to scare the crap out of him like that

Disclaimer- I have/had two cats, lost one to cancer, both fixed females rescued from the cat haven, docile and never leave the yard; but I'm damn sick of the unfixed male cats coming into our yard, eating our cat's food and beating up on them and spraying everything.
Condolences on the loss of your pet pertermac33, I've also found one of our previous cats dead on the door step in years past.
I'll share the mother of all cat stories later on; better get some work done first
