There are a few people on here that use shavings. Many use fleece liners because they are dust free. You can buy fleece from Wal-Mart or any fabric store and cut it to fit the cage. If you want to use a bedding I find Carefresh ultra (it's white and soft) to be least dusty that I have used. Be careful of the other CareFresh varieties especially the colours because they are very dusty. I have never used yesterday's news to fill a cage so I don't know how well it work, doesn't seem very comfy. Another option is a bedding (I believe it's by living world) called fresh and comfy. It's grey and softer than shavings and yesterday's news but not as soft as carefresh. It is harder to find though.
