I never liked paper products for bedding. I used Aspen for a long time before switching to Sani-chips. I couldn't find any aspen in my area that wasn't crazy dusty. Sani-chips have not been dusty at all for me. I've gone through 2 12 cubic feet bags of it ($10 each) and I don't see myself switching back. It almost clumps when wet, making spot cleaning a breeze.
