Using Shredded Junk Mail as Gerbil Bedding

After my son's gerbil chewed up every toy, exercise wheel, and bowl in his cage I decided maybe some junk mail could occupy him. Then it occurred to me, I don't need to purchase bedding for him any more! The junk mail, unwanted credit cards, and anything else with personal information we wanted to dispose of could be shredded by our beloved Herbie. It's a win, win, win situation. We get rid of stuff! We save money on bedding! And our little critter is a happy critter!
