There are limitations to the bandwidth available in the cat distribution network which I don't think have ever been studied adequately. There's probably a grant that could be applied for in there somewhere. There's probably some interesting research to be done in cat distribution network congestion too.

I did some computer vision research, and an unpublished (though posted on a blog) paper in the area of feline toe bean rejection on a multi-touch display in a predator/prey simulated environment, i.e. a touch screen display with a virtual mouse (prey) interacted with by a real cat AKA "an expensive cat toy."
