Out of cage question..

For playtime or out of cage time, I have 5' panels that allow her to roam free and yet gives me the security to know she isn't roaming free around the house. I am always with her as she hasn't learned to come to me yet.

I have seen videos where the chins roam free and yet there doesn't appear to be any droppings. When Sunshine is out of her cage, droppings are everywhere.

Is there something that I need to do differently regarding her droppings?
