Quality varies between the packs
I've been using this litter for my cats for years and I'm satisfied with it. Unfortunately, the quality of the pellets varies from time to time—the last batch was smaller and crumbled too quickly, so I went through it faster than usual.
Important to mention: this litter is meant for sieve toilets! It turns to dust when it gets wet and falls through the sieve. It does this job well, smells like wood, is more environmentally friendly, and (for me) less work than clumping litter.
