If you want no dust then some kind of pellet litter would be best, like corn or pine pellets. My cats hate that texture though, so we had to find one with a similar texture to clay litter. I worked at a pet supply/food store for a couple years and tried a bunch of litters, nothing with a granular texture is truly dust-free, and I found clay litter claims of being “low dust” to be complete bullshit. I settled on Sustainably Yours Large Grain litter, it’s corn based. The large grain really reduces the dust, I get a little bit when emptying the bag but the large grain doesn’t throw dust when they dig around in it. It also clumps pretty well.

I am a fan of Dr. Elsey's Ultra Unscented Clumping Clay Cat Litter.

World's Best clumps and is unscented. It's corn, so there's no clay or silica dust, but it does make its own kind of corn dust, which my previous cat tracked everywhere after thoroughly digging and burying. My present cat just tiptoes in, pees, poos, and tiptoes away, leaving the poo perched proud. It gets my attention to scoop it! But at least no dust gets tracked.

"Sustainably Yours" is the best I've tried. It's even endorsed by Jackson Galaxy.

I've had great luck with pine- and corn-based cat litters for low/no scent and low/no dust. Only problem is that they usually don't clump, though they do make ones which do. Oh, and they're all much lighter than the normal stuff. I'd say give one of those a try.

1. wood pellet. if you buy it packaged for horse stall bedding instead of cat litter you can get 40 lb for $6. requires a special litter box because it's different from the clump and scoop type.

2. if you don't want to change your litter box, you want Naturally Fresh Walnut shell Quick Clumping. please remember not to use clumping litter with small kittens

Pretty Litter. Its exceptional.

I like feline pine litter

Purina had a good one that was pellets made from recycled paper. Think it was called yesterday's news. I haven't seen it in my local stores in a while though.

Blaine's farm and fleet brand. Cheapest clumping litter I ever found, dust free and unscented. It worked great.

Saddly I moved and now it isn't convient to buy.

Petco carries a "sofresh" litter that you can refill. Its unscented and does just fine keeping smells down. If i smell anything then i probably forgot to empty it.

Not particularly low dust but also not any worse than purina or others i've used. And its cheap due to refilling. I have a few petcos that i pass weekly regardless so its pretty convenient for me, at least.

We use this stuff, and it meets your requirements. I like it more than anything else we have used
