I cover about a third of mine roughly, with a Russian he might chew what’s on top so you could use the boredom breaker mats like Beryl said or the cardboard, I’ve got some old fleece hammocks on mine but I wouldn’t use that with anything but Chinese.I was thinking of covering some parts of Albert's cage roof but wasn't sure if it was a good idea. Could you please post some photos of what your cage roofs look like?
