Aww don't worry about that it is normal and the design of the Rody Savic Duna means you wont get a peek for a few days probably as he will wait until it is very dark and quiet before sneeking out for a drink and some food. Leave him in his cage until Sunday with the only interference being to put fresh food and water in daily. Frustrating I can bet for you and your son. But you can think up names in the meantime
