Yes, I use Arm and Hammer Easy Flush. I love it! Just plop the clumps into the toilet and flush. It's pretty fine though, so it seems to track. It controls odor quite well, although, one of my cats doesn't bury so his #2 still smells. I don't use any deoderizer or anything. I very rarely need to change the entire box, so it's economical. One of my cats pees down the side, so I just put the litter into another box, scrub and replace the litter. Some Wal-Marts have it, but I think Petsmart has a slightly better price.
We just bought it and boy does it get rid of the odor!! And it flushes down so easily! I bought it at Fry's Marketplace for $5.99. I just can't get over the fact that after she uses it there is absolutely no odor, even when she does #2!!
