Stop feeding her by the clock. Except for mornings when you both have to go to work. I feed mine anywhere between 7-10 pm sometimes later if I'm out late somewhere. It doesn't do them any harm. In fact I find the later I feed them, Holly eats better. She's a PITA eater normally but if I feed her late when she's hungry, she usually eats all her food instead of sitting around looking at it.She is pretty much fed like clockwork at 7am and 7pm every day. Do you think with the change in the hour that the extra hour she has to wait in the morning is causing it?
Are you feeding her anything different lately to cause the vomiting?
