I feed both of mine just under 1/2 cup per day... I use a 1/4 cup scooper and *almost* fill it for breakfast and dinner... they are just under 5 pounds, and just under 6 pounds.
They are both very active... so they need a little more then some others their size... they are both in great shape... if they are really quiet for a few days and start to put on a little bit of weight, I adjust accordingly... I am always feeling them to make sure they feel just right.
