Tried loads, this is my favourite!
I've tried several different cat litters including World's Best, Everclean, Catsan and others. I found Everclean to be very good but rather expensive and a pain to wash the litter tray because the clay seemed to clog up the drains no matter how little of it was left to wash off. Oko Plus is by far my favourite. My two bengals love it, it holds odour well, it lasts for ages and is very reasonably priced compared to other brands. I'd definitely recommend this and will certainly be sticking to it. The fact it's organic and biodegradable is good too as I have peace of mind knowing I'm not polluting the environment with substances that don't break down over time.
