I've switched to a new brand of food, and I've been feeding them the recommended amount, 1/2 cup per day. The problem is that my babies are starving! Their food is gone 2 hrs after I put it down, and they are always bugging us for food! They get a pouch of wet food in the evenings, but during the day, they're driving us nuts! I do feed Jorin a few veggies, especially mushrooms, cucumbers, and broccoli, but Tiger won't touch these.
