Anthony doesn't have a sense of what is and is not acceptable to eat--similar to an infant.  We are never surprised, for example, when he sees a piece of gum on a retail store floor and pops it in his mouth before we can stop him.  Our attempts to intervene regularly upset him, so we are to the point of reluctantly looking the other way.  

Today he was apparently still hungry and not satisfied with his second serving of dinner, so he helped himself to some rabbit pellets in our pet's cage.  My wife re-heated his food and added more salt plus a little cayenne pepper to renew his interest.  He promptly finished it.
