Just that really.
A random cat has taken to crapping in my garden - occupational hazard of living in a city, I guess.
I know there are a variety of products, home made and otherwise, you can use as a deterrent. However my dog uses the garden, including to toilet. So obviously I don't want anything dangerous to the pup, and I don't want to put her off doing her business (especially right now, when other options to go out are so limited with the heat). So e.g. one of those devices with high pitched sounds might bother my doggy as well. And chemical products might be harmful
Any bright ideas?
Thanks!
