We have found this to be the best kitty litter we've ever come across. There's no waste, you don't throw away big clumps of litter, the urine evaporates in the poop and doesn't clean onto it very much. So what you put in at the beginning of the month is about what you have left at the end of the month. With our kitty, we have found that it lasts more than a month before it needs to be changed, but we change it as often as a new delivery comes. It's great for monitoring your kitties health and it doesn't weigh a ton like most clay or scoopable litters. It's definitely worth the money that you'll spend on it!
I've recommended it to friends, and they purchased it and are so pleased with it and thankful that I turned them on to this product!
Bottom Line: Yes, I would recommend this to a friend
