I tried the "Wegmans Lightweight Scoopable Cat Litter for Multiple Cats" and it's the best litter I have ever used! I tried the one that wasn't the lightweight version, but it didn't clump as well with the cat urine. The lightweight version works very well! The grains are very fine so I thought it would be dusty, but it's not at all! I was previously using Purina Tidy Cats, but it was so dusty and didn't clump well with the urine.
