And should the smooth perimeter be about 4' high? I have very sandy, easily dug soil and my ferrets have never gone deeper than 3 feet. (and let me tell you, I think they were all miners in a previous life!) I have a champion leaper, Stylson, who can scale any barricade, but 4 feet would be too much for him.
