Why does my kitten like to eat such weird things?

I’ve had cats pretty much all my life, and have never had one who eats the things Mouse does. She caught a dropped sour cream and onion potato chip, and devoured it. Ever since, she tries her damnedest to climb into any chip bag she can find. We can’t leave any kind of bread out of the cabinet, because she eats through the wrapper to get to it and gorges herself. Her favorite is potato bread, but she’ll eat any kind she can get. What’s up with that?
