You do realise that cat owners can't control their cats' behaviour and that cats themselves aren't actually aware that you consider a particular space yours?
As fas as they're concerned, it's a place for them to leave a message for other cats- it's not an attack on you/your garden!
It always amazes me that gardeners, who I presume are nature lovers, get angry about an animal's natural behaviour.
Live and let live! It's only poo!
