I feed monty in a cardboard box (avon box). We don't want him associating food with his territory because we dont want to get bit when we reach into the tank to get him out. We handle him daily.
Anyway, it is also nice that as soon as Monty realizes that he is in the cardboard box he knows it is time to eat. He actually start looking for the rat before we even get the bag near the box.
One time he grabbed the rat before the rat hit the bottom of the box.
