pmcalk, Speaking from experience: rodents can chew through nearly any container if they want what is inside badly enough. Unfortunately, this means leaving the food items out of your compost heap (with the exception of coffee grounds). Leaves, grass clippings and other yard waste will not attract them.
Try making a small indention in your compost pile then covering the pile of food scraps with dirt. If you don't have meats or fats, usually rodents will not be a problem.
Compost doesn't attract rats, things like dog food do. Compost piles are just easy places for a rodent problem to be seen.
Tulsa has a rat problem this spring, especially in mid-town. There are not many solutions that are easy.
I have composted egg shells, potato peels, vegetable peels, and coffee grounds with no rodent problem.
