This is a great option!
I grew up on a farm and we always had a few cats around the barn.
Not a common prob, but every now and then it would be, the cats would try to
climb up under the hood of a vehicle that had been running, liked the warmth
I guess.
Of course, if they were still there when the vehicle started again, they
were goners.
Thankfully that never happened at our house, but a neighbour who it had
happened to suggested spraying them with the garden hose on a strong
setting, so they got wet, and it stung a bit too.
We did that and the cat never when near the vehicle again.
Only thing wrong with this is you have to sit around and wait for them to
come to make it effective.

Alternately, I found something at the nursery called "get off my garden" and
it is a smelly greenish gel that you spray on your perimiter.
I got it because i had a dog tearing the garbage a few times.
Sprayed it once on the bag itself, and the dog never bothered my driveway
again.
Now I still have this whole bottle of stuff...and no problem animals to make
me bring it out again.
I didn't find it too bad to my nose, but apparently to the animal, it is
like marking territory, and kept them away.
Might be worth a try?

Good luck

I am looking for humane, non-harmful ways to keep the neighborhood
cats out of my yard. I don't want to trap the cats eithers. Any
suggestions?

Cats hate getting wet. Get a kid's "Soaker" and spray the little devils.
