If you prefer to have your BP eat rats in the long run, then start buying him appropriately sized rats. If you are able to get mice cheaper and it doesn't bother you to feed mice in the long run, then go for it. Weight(mass) of the feeders is not a suitable way of being able to tell what size is/isn't appropriate. Use the 'girth' method.
