Had Nyala for 4 months now. She was free fed so her bowl was always full. 2-3 cups per day but she would always leave a cup. She ate when she wanted which was fine. Nothing is wrong with that. But if I would take example like a piece of cheese cut it up in mini pieces teaspoon mix it with her kibbles, she would eat the whole bowl in one shot. She on home cooking now and trust me she sure emptys her bowl.
