First off, I applaud you for taking the time to ham-proof your room so your little one can have the amazing experience of free-ranging! How old is your hamster? I notice that young hamsters have a tendency to be a bit more mischievous when out of their cages. Like others suggested, block off the corners and add edible toys and other things to keep her busy. Add lots of cardboard boxes and tubes for her to crawl about in and on. A dig box can be fun too, and spreading cheerios about the floor could help keep her busy and simulates natural foraging. Have fun with your ham and have fun designing cool cardboard obstacle courses!
