They keep waiting on a treat or human food, they are afraid to eat or spoiled to treats. My girl wont eat, then I will give her a treat & then she will. Or I will hand feed her. because if not yes they will throw up because of the empty stomach sickness. So just a few spoonfuls of yogurt or a favorite treat to spark a appetite will help. And ven though you leave the food down doesnt mean they will eat when their hungary, I remeber making my kids food then chasing them around making them eat because if not they wouldnt.
