While I worked on some flower arrangements, my fantastic boyfriend spent his time constructing this gigantic playhouse from cardboard and duct tape for our Chinese Dwarf Hamster, Quentin. It has tubes for him to crawl through, bridges to cross, and ladders to climb. One important addition the bf made was to add safety railings to all the bridges and ledges on the highest levels. This helps our teensy hamster feel safe enough to use them.
