I thought PaPurr was a great choice at first, and even bought a second bag, thinking that I would get used to the strong ink smell - I never did. The reason I stopped using it, though, was because the last batch I bought contained litter that didn't clump as well as the first and fell apart into soggy droplets all over the clean litter as I tried to scoop. I ended up using paper towels to scoop the stuff out. The cats did like it, and it is pretty much dustless. Will they EVER develop the perfect litter for all of us, cats and humans?!
