Here's the link to all the flavors of Fresh Step clumping litter, including the perfume free:http://www.freshstep.com/prodscoopable.php#perfume
Don't quote me, but I'm pretty sure my grocery store carries it. They just ran a promo on the Fresh Step - 21 pound box for $6.99 with the store's card. That's cheaper than the store brand litter. I tested the Fresh Step against the Cat's Pride brand at WalMart -- a small bowl of each, dumping in a measure tablespoon of water. The Fresh Step clumped faster, harder, dryer.
They had all the flavors. I bought about six boxes of the regular (scented). My wife bought about six boxes of the multi-cat flavor. If I had been thinking, I would have bought some of the unscented to try as I'm not a big fan of the smell of the scented litters, but honestly shopping for this cat litter stuff is kind of overwhelming for an old guy like me. I just gave my wife a list of all the varieties, so if she sees a bargain on sale, to grab some -- regular, unscented, multi-cat -- it's all the same stuff when you get right down to it.
I can't remember which versions WalMart sells.
I haven't really noticed any particularly bad dust issue.
BTW, Scoops Away brand is also owned by Chlorox. I strongly suspect that Scoops Away and Fresh Step are both made in the same factory and, for all intents and purposes, are probably the same product. They also make an unscented.
