repelling stray cat

repelling stray cat

There's a local stray cat who keeps using my garden as a toilet. Ideally, I'd catch him, take him to the vet, and then to a shelter, but I doubt I'll be able to accomplish that. I tried putting citrus peel in my garden last year, and it was not as effective as I might've hoped. I was considering using repellent evaporators this year, but I don't know how well they work. Any experiences with them? Recommendations for other things to try?
