A half cup for the whole day should be plenty, unless he's large. Ranger ate 1/4 cup 2x per day for a year until we started raw a few months ago. If your worried about it, you could leave food out all the time which will let him eat when he wants to.
I don't do that because my boys are PIGGIES and would eat till they popped!!!
Careful with the nutri-cal, often times it can supress the appetite... |
