Good Litter but ... **NO LONGER FLUSHABLE!!**
I've happily used Cat's Best Original for *10 years*, flushing it without problem. All the granules used to be really soft, easily crumbling to dust between your fingers. However, it appears the formulation has changed; it now contains small but very hard granules of wood chip that DO NOT DISSOLVE. I've just forked out *hundreds* to clear a drain blockage caused by this product. It's still a good litter (lightweight, easy-to-remove clumps) but do yourself a favour: PUT IT IN THE BIN!
