little bugger....

That bugz bunny doesn't seem to understand that you don't pee where you sleep or eat.   He is quite finicky about what he eats and when he eats it but not picky at all about when or where it comes out the other end.  We have a large rabbit hutch with a grate over 2/3 of  the bottom  and a small little house with a wood floor that covers the other third.  For some reason he has decide to only live in the house part.  How on earth do you potty train a rabbit?  Help!
