How long have you let her go without eating? My Oliver did this same thing, the vet told me to just ignore him. He went three days without eating, but now he'll eat regardless of me being around. For some reason I put the food on a plate and he liked that better, now he is back to a bowl. I think they probably do this because they prefer you feeding them, but they're not gonna let themselves starve to death, I would suggest going a few days. What happens if there is a time when you can't be around?
