The is litter is pretty good, although as other reviewers have said, the clumps it forms are rock solid . Still, they are easy to remove from the tray. It has a smell which helps in disguising cat poo smell but it is too chemical a smell for me. Sadly my elderly cat who has a lot of allergies started to lose the fur off her feet and I've had to switch back to the old litter. That doesn't mean there's anything wrong with this one.
