Take it to the next level and make it feel like the cattle it is. place a water trough in front of it so it can bend down and drink whenever it's thirsty. When it finally is free of its self-induced confinement, it will be so ashamed it might actually stay human. edit: if you want to be super mean, put a feed trough in front of it as well, but only put vegetables with a low net-carb index in it, so basically just leafy greens. It will eventually break and start shoveling the veggies down it's maw just to eat something. Now you've trained it to eat healthier.
