Kitty litter... well I used several kinds, all in varying degrees of stinkiness- UGH!
Remember I live in an apartment, so it HAS to be as non stinky as possible.
The best I have tried and use regularly is Swheat scoop
It's a wheat based product, safer for environment (renewable resource, biodegrades) .. safer for little kitties (The regular scooping litter is not really good for young kittens because of the dust.. gets into their eyes and noses. Wheat based so it's safe if the kitties try to eat the litter. )
It lasts for a few weeks with regular daily scooping.
Costs a bit more than the other brands.. but when it comes to stinkiness

it's worth the extra $. The poos still stink, but the pee gets neutralized, it smells very sweet when it's wet. It clumps very well too.. much better than the cheapo litters.
The problem is... it's not readily available at supermarkets or places like
Walmart. Natural food stores, Petco, Pet Smart, Target are the only places you can find it.
