I use this brand for my rats when my regular distributor is slow with the really big bags I get.
I've noticed changes several times over the past couple of years in their shredding process which at times makes this aspen REALLY dusty.
I've bought it when it was large chunks and when it was basically shredded.
They can't seem to make up their minds on how they want to produce it, or the shredder blades get dull and the aspen comes out different depending on which shredder they use.
I generally toss them since there is only a few of them in a bag.
