Turns to dust = easy to clean
I've read a few of the reviews on here and I think it's really a matter of preference. This litter does indeed turn to dust, but I prefer this as it doesn't stick to my litter tray, making it easier to clean.
I have three cats in my household and find I have to empty two of the trays every 4 days as they wee in these and it does cause smell. However, I didn't think the clumping litter was any better. I found the clumping litter difficult to remove and I had to empty the tray just as frequently.
