I used it for his Pussiness, and I would never use anything else. He wasn't neutered until almost 9 years old, and he had that nasty old geriatric male cat pee smell. It was horrible. The pine litter cut the smell in half, and he seemed to like it a lot.
It doesn't clump, but he wouldn't use clumping litter anyway, and he didn't dig much (or even cover most of the time) so I didn't have a dust problem.
