Don't buy unless you want it EVERYWHERE
Great at clumping, not as smelly but still whiffs after a week, however OMG it ends up everywhere - it's so fine they just scrape it out of the box, gets flicked about a metre with lively cats!!! you have to hoover daily around box, cats then refused to use as didn't like walking on it to get to box - so had to lay down sheepskin style rug around box - wish you could show photos as I've got several!!! Not happy!
