I have Chives, Garlic Chives, Garlic and Onions growing in my garden, the kids just ignore them, personally, I wouldn't worry too much, I have had them since before the present lot of cats and they have all ignored them. As well as the Bay, Rosemary, Basil (purple, italian and thai), Coriander, Thyme and Sage. They do love the Catnip though
