I agree with stranger. My ex-stray Liebchen, who was literally starving when I took him in (you should have seen his terrified scuttling around dumpsters, painfully thin and dragging his dislocated hip) used to eat and eat and eat and EAT. But eventually his weight settled down at "slightly pudgy" and there he remained until his final illness. If Smokey isn't seriously obese, I wouldn't worry too much.
