Never knew that.  I may have to try it.  Don't recall seeing too many 
osage oranges up here around Charleston, though we had plenty in Hinton.

You, sir, are not the first to ask that question.  My answer is I do not 
know.  However, replacing litter with saw dust and letting the little 
darlings go to town in it should do the job.  Extract nice wet clumps, 
store in plastic container.  Pack metal into it, adding water if things 
have dried out... voyluh!  Cat pee will turn 440 stainless a perfect jet 
black... or at least *my* cat's pee did.  YMMV, I suppose.
