I also have to give a big nod for beaver consumption. Hmm, no wonder I'm such a big bastard.
You might also look into buffalo meat. One of my favs. There have been numerous threads on exotic meat benefits, including buffalo.
I found this site interesting...
My advice: Open several windows, search for your animal of choice, and flip back and forth watching the marking dot move around the caloric ratio pyramid (make sure you are evaluating based on comparable serving sizes).
elk, venison, bison/buffalo, ostrich, emu, many more...and of course sexy music beaver. Yeah, baby. (autin powers)
