yep on this or feeding them quietly in your room when no one is looking. Maybe even get a mini fridge for your room and store your chicken wings, etc in there so the roomies won't eat it themselves.*shrug* I'd still feed my dogs raw, what's wrong w/ them eating in their crates? easy to clean and touches nothing anyone else touches.
On a sidenote, they are making much to big of an issue over this. Why should they care what you feed your dogs as long as it doesn't affect them? That's a little weird.
