Ebbie, I did that with seven cats. Walked them all on leashes, then eventually got to where I could open the front door, let them out onto the steps and little patch of grass. They would all stay there where the dog and I watched over them. When I clapped my hands and said, "Inside" in they would go. It was quite the sight. I have pix of them lounging on the steps. If I can find them I will post a link.
