You're probably right, SpeckledHen. Shavings are probbaly better. I got my sawdust free for the hauling and used it in my barn stalls as well, so it was practical for me. Because of this, I don't have much experience with shavings except what was mixed in with the sawdust. However, in defense of it, I will say it stayed fairly dry and I could stir it or take out the dirty/wet spots and it would last for some time. I suspect the same could be said for shavings.
