I don’t think there is such a thing? I recently lost my cat that had some nasty respiratory issue. Could have been asthma or possibly cancer.
Anyway, I had been using grass litter and changed to paper just to cover that base in case the grass was aggravating her condition. The grass is actually quite low dust out of the bag but of course as it is used and scooped, it breaks down into dust.
The paper is dusty! It is the clumping stuff but when you pour it out of the bag, there is quite a bit of dust. Silica crystal litters I think, also break down into dust. I detest clay litter and found the same thing with Dr Elsey’s Ultra. It was horrible.
As soon as I am done with the paper litter (still have one cat), I am going back to the grass litter. It clumps tightly and I just need to change it out completely more often (every 3 months) before it breaks down so much.
Good luck with finding no dust.
