I tried flushing World’s Best Cat Litter a few times, and while it technically works, I stopped doing it. It broke down fine, but I didn’t feel comfortable long-term. As a regular scoop-and-trash litter, though, it’s solid. Low dust, decent clumping, and lighter bags. I run a multi-cat home with Nutra Nuggets dry food, and odor control has been acceptable as long as I scoop twice a day.
