I posted with the same problem we were having with Kiki not too long ago. She would just throw up out of the blue and then be fine. I brought her to the vet and he said it was probably too many hours without food during the night and to try to give her a snack before bed. Easier said than done ... the food is out, she just eats if she wants and other times turns her nose to it. I've been adding a teaspoon of Merrick's Grammy's Pot Pie to her dry food and she seems to be loving her food now.
