Is there any good ways to avoid neighbors' cats going into our vegetable garden as their littering place? In the past, I've seen a plant called Coleus Canina "Scardy Cat" that said can keep cats away. But I no longer find them in Vancouver (unless I went to the nurseries at the wrong time to pick them up). Well, we've tried using moth balls under the tree and it seemed to work and kept them away. But we don't want to use moth balls in the vegetable garden. I hope to look for some natural remedies that can keep them off. Thanks!
