How to keep the mess down? Well, I usually keep Squeaky, my Khaki Campbell in a cage that has a steel sheet of metal on the side of the cage next to the wall. Her poop and food ends up on the steel and not on the wall. The cage sits on a tray that has horse pellets in it to absorb the water, etc. and reduce the smell. When it is time to change the pellets, they turn to sawdust. I let Squeaky out of her cage when I get home from class and or work. She does poop on the floor, for this issue I usually wipe it up and sanitize to area. But Squeaky is very sociable and she bugs me to death. She knows my voice and walking pattern and quacks at me when I am a floor level above her.
