I have been using this product for more than ten years and have had great success with it. My cats are happy and so am I. I live on the third floor and am eighty years old. Flushable litter is perfect for me. I've tried other types of flushable litter but my cats didn't like it. Here's a tip. Instead of the standard litter boxes, I purchased an 'under the bed' storage box with wheels and use it as a litter box. I have two cats and it gives them plenty of room. Heaven help poor kitties who have to go into those covered boxes where they can barely turn around. Just sayin'
