Oh, what the hell, let's make this a conversation. So, there is a thing called rabbit starvation. It happens when you only consume meat and don't supplement with the other things you need. After a week, or less, of snacking on Rudy, you'd die anyway, from a lack of essential nutrients that you get from plants.
The best option would be to eat the whole rabbit, including the intestines and contents. That would be difficult with Rudy, and probably not effective since his last meal was probably Mountain House. It would honestly be better to eat the rabbit, squirrel, mouse, etc.
Or you would get Kuru. And die later on.
Of course, I am assuming you know and are good buds with a guy named Rudy, and I'm also assuming he dies an untimely death in an extreme situation. Let's say you two are in Wyoming............camping.....on a sheep ranch......
