Tigerino Premium Cat Litter – Lemongrass Scented

We've been using this litter for at least ten years and I was always so satisfied. Now, in a multi-cat household, it's no longer usable. The pellets crumble, which never used to happen! It never had this construction debris smell, this chalky odour, and even though the toilet is absolutely clean, freshly topped up and only used once, it reeks of that chalky muck!
