SWheat Scoop
Best cat litter ever. I was shocked to find out that clay litters aren't biodegradable, are carcinogens, can cause urinary tract problems in cats, and can cause respiratory problems in humans and cats. I had noticed that they track the scoopable-clay litter all over the bathroom, and sometimes I feel like I'm spending many hours scrubbing dust and clay off the bathroom floors.
Swheat scoop rules. No more dust. They hardly track any of it anywhere. It smells fine (a little like wet bread, actually), and it clumps pretty well. It's more expensive than the clumping clay we used to get, but it's so much better. I spend so much less time cleaning (and inhaling litter dust). They also make clumping litter from corn, but that's even more expensive than the wheat litter.
