Cats habituated to carbohydrates might touch that stuff, but most won't.
Of course cats that are heavy carbohydrate eaters tend to be obese and end up with diabetes. As they're even less set up for eating such than humans.
I used to have a cat that would steal chunks of sweet potato off my plate when I was eating dinner. You never know.
Heck, I have a RABBIT that will try to eat the cat's WET food - straight up meat and fish bits - if we put it within reach of her.
I have 7, and like people, every one of them is different. One is crazy about parsley, another yogurt and cheese, one goes mental as soon as she starts smelling chicken or turkey cooking in the kitchen. One of them loves brown bread, another one loves chestnut and one of them goes wild over sashimi. The last one will eat absolutely anything.
