No offense taken by this I hope, but cats aren't like fish..feed them once and you're done. I have 6 cats at my house, one not being my own. Each has their own taste for foods, but we keep out dry food for them so if for some reason we aren't around they can still eat. Cats and dogs generally need a breakfast and dinner just as we humans do. I know for myself, if I get overhungry and then I finally eat I feel really bad afterwards and sometime get sick. It sounds like your kitty may have the same problem. I'd leave out some dry food for her and then give her a can for dinner.
