I have fenced my two boys off with weld mesh on wooden frames and tied to their cage (metal top and plastic bottom). They have a laminated floor with cardboard on top and carpet on that. They are great chewers so have loads of cardboard and a dig box and various toys plus i scatter feed them to keep them occupied. The other two are fenced off with a puppy pen held in place by heavy furniture and breeze blocks and they have the same flooring as the boys. Good luck with your new rabbits. Where are you getting them from? :wave:
