Rabbit raiser here! And ditto what everyone else said, use the poop!
I spent years raising meat rabbits (I recommend New Zealand Whites for good meat production, Dave/Trish) and they provided meat, fur, and manure. I never made any mittens or muffs like you did, bonehead, but just salt-cured the pelts and used them as "doilies" (anyone else remember what those are?) or would give/sell them to friends to do with as they wished. Now I have some cross New Zealand/San Juan rabbits I'm working with.
All in all, shadygreenthumb, jump on that excrement (well, not literally)! It's great to have a pet that pays its rent in some form or fashion, eh?
