Stick with OKO, this is no substitute.
I thought i'd buy this as a change from the usual OKO Plus as it was on offer.
On first impressions it looks exactly the same as OKO Plus. Unfortunately the performance doesn't match or beat it.
My cat did a pee in the corner of the litter box, I left it for 5 mins then went and had a look. The first thing I noticed was that there was pee pooled on the top of the litter rather than being fully absorbed. It did not clump well - the pee ball was very wet/fragile and falling apart when I removed it. It was like removing a dollop of soft porridge.
I've previously had the same issues with the Tigerino brand.
