Our furry family and sanctuary buns have quadrants, exercise pens, or an XLG d/k crate as private bedroom spaces. Multiple hop levels or a sit/nap shelf and a large litter pan to accomodate their size and hay is beneficial. Add the toys, water bowl, and lounging area to stretch out.
A private bedroom space or housing unit helps to keep chewers from chewing woodwork, indigestible material, and valuable material goods when you are not home to supervise.
