Professional Classic Cat Litter with Active Carbon

I've ordered this litter twice now to test it out for a bit longer. My goal was to find a litter that would make the flat smell less like a cat toilet and wouldn't get spread around as much by the long fur of my Maine Coons. The second point actually improved. But unfortunately, the smell is really unpleasant. Now not only does the flat stink, but with this litter, even the long-haired cats themselves smell strongly like a cat toilet. Not suitable for me.
