Good cat litter, ranked by what we measured
We weighed the dust that goes up on the pour, dropped the clumps to see which held, and priced every bag by the day. Here is where all 17 landed.

















Fig. 1: every litter on the board, in rank order.
The short answer
If you read nothing else.

The full board
Score order. Shorter dust and cost bars are better; a longer clumps bar is better. A dashed bar means we have not run that test yet.
