If your garden is fairly small then you could try a water scarecrow to keep cats away. My daughter was having terrible cat mess problems before she installed one. Within a couple of hours of putting it in the cats had got wise to its existence and now they walk along the boundary walls but never come into the garden. The only downside is making sure the humans remember it's on before they venture out!
I'm not sure if it would work for foxes though.
