I also switched the shavings from the left side of the cage to under the hammock. That was much more of a success, especially this summer. The hot, humid weather makes for a damper and smellier cage; since that's the corner they tended to pee in anyway, I could scoop it out and replace the shavings daily. It made everyone in the house happier.
This week, I moved the fleece forest downstairs to see how they liked it. It's certainly getting lots of use, given the pile of poo underneath. However, I liked it best upstairs, and will probably move it up there the next time I swap out their fleece.
