I've caged mine but it seems there was no point. They just aren't growing. My Early Girl has a tomato growing! But the plant itself is the same height as when I bought it, in early May. I wonder if it's too little sun, too little rain, or both or neither that caused the plant to not grow. Frustrating. My other tomatos, like a Fourth of July and so on, also did not grow at all, so they are about, oh, 5 inches tall?
