My local cat store ordered this stuff for me. It's not cheap, roughly 50% more than world's best. About $1.50 per lb. That is a lot, but if it works well, may be worth it.
It claims to be twice as absorbant as clay litter and to last longer than competition.
It is some sort of corn-based product like world's best, but has much finer particles and no dust that I can tell so far at all. It comes in 10lb bags and contains the nature's miracle enzymes.
It has a kind of orangish hue to it. The particles are orange or black.
The cats used it within 15 minutes and used it fairly heavily. To the point that I had to scoop it. The main issue I have right now is that no matter what litter I use, my calico will sometimes not properly bury her stuff. She tries to bury it in her own unique way sometimes, which involves pawing OUTSIDE of the litterbox. This litter does not help with that problem. Maybe no litter will.
The litter itself smells absolutely wonderful. Kind of like bananas and pine. I'll update this thread in a week or so. Hopefully it will mask odor and still smell great.
The particles seem perfect to me. Really fine grained, but not to the point of being dust-like. No dust when I poured it in, and no tracking or dust when I scoop. Unlike arm & hammer and everclean, it does not clump "big" with urine, meaning that the clumps were not too huge.
