One of our neighbours has two cats, they are quite nice and child-friendly (as far as we've seen) but they use our garden and front lawn as their littler tray, unfortunately. They're quite brave as well, we can be right there and they won't move...
I've never had a garden before, so I have no idea which option is best (there are so many!), gels, pepper powder, garlic powder, sprays, sonic repeller, etc.
Any suggestions/advice will be hugely appreciated!
