Hello,
 
I have a wooden cage that I built for my two guys, Jasper and Merlin, and on
the bottom I have a bathroom rug ($10.00).  I have two I rotate with and
when one gets dirty I just throw it in the wash.  It is also nice and plush
so they love to jump around and wrestle.  Hope this helps someone.
