I just cleaned Neo & Morpheus's cage, which I do about every 3rd day since I still have them in the so-called "Extra Large" SuperPet cage. I still haven't quite settled on my C&C plan. (What size, where to put it, 2nd level size, coroplast, etc.) When I put them back in it, they run around checking everything out and making little chirpy noises and popping about. It's sooo cute to see them so happy with a clean house!
