I think it's far better than Oko. It's exactly the same stuff, so has all of its good points, but as it's pellets and not dust, it has none of its bad points. Well worth the having, if you ask me.

i use this Lightweight Non-Clumping Antibacterial Cat Litter 25ltr by Pets at Home | Pets at Home

We have two trays for our two boys and we barely get any smells as long as we scoop it every morning. Seems to last well i only need to do a full change every 10-14 days.

I really recommend Oz-Pet, the poo stops stinking straight away after you put it in the bin, and it doesn't track at all! And the poo doesn't stink as bad if you feed Leo on Royal Canin!
