Woodshavings aren't an ideal bedding for small animals anyway, as they're quite dusty, and also the most common type of wood used realises phenols which can actually cause liver damage. They're rarely used by rat owners these days (especially as rats are prone to respiratory problems) but thankfully are being used less and less for other animals too. I think that this will hopefully encourage petshops and companies to sell/produce more animal friendly litters.
I use Ecopetbed for all my animals, which is shredded cardboard. No dust, works well and no phenols or scent which could be harmful. I also use newspaper (bottom of the puppy pen for bun), and shredded paper (bedding for the rats and hamster, and in the bunny litter tray)
