Good but...
Very effective, but the grains are really, really fine. So they stick easily to the cat’s paws and when it goes wandering around, it spreads them everywhere. A few grains here and there is okay, but after two or three trips, you definitely need to get the hoover out for a good clean. I’ve got two full bags left, I’m going to give them away because I’m fed up with cleaning every day. ;)
