We used to use the white not clumping, but found the Meier brand (grocery store brand) in the clumpable no scent to be gray. And it's fairly reasonable too! If you have a Meiers in your area I'd check it out.
We have NO pee-ers now. Maybe cause there's less of them? We only have 11 now. Maybe the litter helped using clumpable? Maybe a bit of both. But either way it is SO nice.
We renovated the upstairs and it's staying perfectly clean! Love it!
Good luck on the litter choice.
