I dunno...hunger makes people crazy. I'd imagine maybe something more along the lines of the dog and the cat.
Karen would be the dog, which is usually overpowering of the cat, and Noob the cat would usually be more likely to run from the dog. However, under such circumstances, things might change. I mean Karen would, of course, assault Noob with tickling to get it for herself (though she would do that without the need for sugar anyway, but it's not in there so much for her), and normally she would dominate since Noob is WAY more submissive. But with hunger driving him, could Noob possible become more aggressive and fight back? Hmmm.....*plans for experiments*
