Full of dust/fine particles. My cat never used it
"As soon as I opened the package and filled the litter box, I knew this was going to be a problem for my cat. From my point of view, this litter was full of dust/tiny fine particles which easily covered/stuck to my hand. When my cat went into the box, he started smelling the litter, then sneezed, and immediately jumped out. He hated it, and never used the litter. It says this litter is 99% dust free, but I would say it is full of dust, even I couldn't stand the dust/fine powdery particles. Never again."
