Rhonni, I just thought of something else. If you do manage to get him inside and he panics and is frantic to get back out, or he escapes, it would be okay to let him go, and a few days later try again. He will come back as long as there's food to eat, and he will understand that although he was frightened, he wasn't hurt, and that will make it easier to try again. A stray cat will keep returning to any place that has free good food and nothing to physically injure them (like a big dog or such).
