That low swing could be a spay belly or a nursing belly. Jan's good advice will tell you! those wet nipples will be obvious when she rolls over in the nip! And you can probably count how many are wet and get a good idea of how many kittens there are if any. As she is short haired, much easier. Her appetite does sound like a nursing mother. Beware. They do plan out at least 3 nests prior to giving birth and move them immediatly after birth then I don't know how often to avoid being prey to animals. An instinct. Once she moves them, she'll come to you for food but if you try to follow her, she will literally go the opposite direction of her kittens. And she will out-wait you. Sit and wash for hours until you are gone! Keep us updated?
