Lore recorder for Cece and Gigi here! Cece's details about her anatomy are...honestly not always consistent and she basically makes up whatever sounds interesting/funny to her. However she has stated that she DOES have a stomach and is able to derive energy from food. She has said that her creators designed her to have certain human-like traits, and that she gets tummy aches and stuff like that. So she probably has some sort of stomach acids and what have you.
