take out all the plastic shelves and ramps and replace them with kiln dried pine shelves. because it is a tall cage, i would either make a wood platform across the middle with a few boards, or hang a hammock across the middle, half way up (think 'chinnie trampoline', lol).
those small doors are going to be a pain in the tookus come cleaning time.
and don't use the hammock, if it comes with the cage, as that is a ferret hammock and not safe for use with chins. the plastic tray on the cage bottom may need to be wrapped in polar fleece to keep your chin from chewing it.
edit - never mind my comment on the small doors, i now see that the whole side panels open up. that'll make cleaning easy!
