I was just at Walmart buying litter the other day and didn't see it? The one thing I'd worry about is having those little foamy pellets scattered hither and nither. At least the cluping litter stays close to the box.... Pouncer is a litter flinger. I can see him flinging this stuff all throughout the house!

And does it last one month with multiple cats or just one cat. If its $8 a month for one cat... I've currently got 6 cats... and ususally spend $10 a month on litter... with this stuff I'd be spending 4-5 times that amount.
