I live in a downtown area where there are many cats walking around. They used to poop all over my garden, but I think I may have found a solution but I am not sure. I read that cats dislike the smell of coffee. So to experiment, I would cover the pile of cat poop with a large pile of coffee grounds. In my experience so far the cats do not return to poop in that spot like they would before. It is also not illegal to add plants that are poisonous to cats on the border of your property.
