I have used Swheat Scoop for my cats. I switched because the clay litter is so unhealthy for cats to breathe in and for the humans who scoop it! The Swheat Scoop has a really nice smell when you pour it into the box, kind of like a fresh hay field.
You need to make sure that you pour enough of it in the box (at least 3 or 4 inches) because if it gets too low, the pee mixes with the dust of the Swheat Scoop at the bottom and sticks to the bottom of the box. It's not that bad though and with a little scraping you can get it off the bottom.

The other two things that I found were a bit of a challenge were odour control and tracking. If you clean the box a couple times a day and only have one or two cats, I think this would not be an issue. I have 9 cats so I did notice that it didn't control the odour as well as the clay litter.

It seemed to track more than the clay litter and I found little pieces of wheat all over the floor that required daily sweeping. But, when I switched back to the clay, I realized that it tracks quite a bit too and I was sweeping that too.

The two best things about the Swheat Scoop are how healthy it is for cats and people and how 'light' it is to deal with. When you scoop it, each deposit that your cat leaves weighs next to nothing compared to the heaviness of the clay 'balls'. If you have a few boxes to scoop, it makes a real difference and the bag of scoopables that you toss in the trash in the end weighs very little. That is a great feature of this litter.
