I don't think crate feeding him is going to work. First, he eats whenenver he wants, and second, when he eats, he first takes the food out from his dish, scatters it around, and then eats it, making a lot of crumbs.
I don't want him to be sleeping in that. And he has a problem of taking his towels or blankets, and stuffing them into the food and water dishes with his mouth. I have no idea why.
