Had this problem with Bodhi my new kitten. He kept throwing up the dry Science Diet Kitten food minutes after eating. I too tried wet food and like your kitty no problem but I think dry is best as a staple food. I switched him to Wysong, a lower fat but high quality dry kitten food and he's fine. Maybe she feels she has to get her share before the other guys come in .The first ingredients listed on the cat food bag should be meat not cereal products because they are usually listed in what there is most of first. I also gave him some low fat plain yoghurt ( read somewhere this was good for them). Good luck I know how wrrying this can be. Gotta run Maya's figured out how to jump on the piano and is clearing off my knick-knack collection.
