Definitely worth it
I will only ever use this litter now. It clumps really well and as it's flushable, the horrible, smelly task of cleaning the litter box takes about a minute now - the tray is right next to the toilet for this very reason! My kitty is the queen of the household so doesn't bury her doings (if your cat doesn't bury their leavings it means they think of themselves as the leader of the pride!) so I can't comment on odour control, at least for solid leavings. If you only have one cat you probably only need to completely empty and scrub the tray once a month or so, just top it up in-between times after scooping clumps, so it works out a lot cheaper in the long run. It's November now, I bought a giant 15kg bag back in August and we're still using it with about a third of it still left! £40 for about 6 months' use, that's cheaper than using supermarket litter and we don't have to go out and buy it as it can be delivered to our door. Tips I'd give to people considering this litter: 1. Do scoop the clumps once a day, the odour control is good but not *that* good, getting great litter isn't an excuse to be lazy and not clean the tray; 2: Get a large, bucket-shaped scoop to use with this litter as it clumps very well and makes rather large clumps. I have a huge pink Catit scoop (I think this site sells it) that works perfectly; and 3: When flushing, don't put anything else down the loo (no toilet paper or anything, flush it before using it yourself!) as if the clumps are large it will take a bit of time to dissolve and nobody wants a toilet blocked with soggy, used cat litter.
Sorry for the essay, just wanted to make sure other customers are well-informed! (And no I don't work for the company!! :))
