A digging box - tote filled with sand or dirt (black earth / potting soil?) and covered with a lid - make an "escape hole" in the top and bunnies can dig away without making a huge mess! My bun would love this!
I think it would be a great idea to get a thread going with pics of everyones bunny condos/living area/room where there bunny lives. I think this would be great to do for people who need new ideas for there bunny condo or just for p.
