Congrat's on your new hamster BOO! I'm sure it'll keep little BOO preoccupied for hours, bless her!
Another little word of warning - Our daughter used to keep her hamster in her room, until one night the noise of the wheel kept her awake, so she put the cage outside on the landing. Unfortunately, it tugged at my husband's new jeans hanging over the banisters & chewed the bottom of the leg. In the morning, we found her with a belly full of denim & she sadly passed away later that day! Talk about tears at bedtime....
