Kitty TWIST'R® Classic

We recently purchased the Kitty TWIST'R Classic, and we love it. Honestly wish we had bought the Multi kitty TWIST'R instead, but here we are...lol. The scoop that come with it fits the opening on the unit perfectly so litter falls directly into the opening, not along the mouth of the opening or onto the floor. Using our old, wide flat scoop gets the bulk of the waste into the opening but little bits of litter fall around the opening, creating a mess to clean up. It holds odors great; we never smell anything emanating from it. It's a great product, I highly recommend it! Wish we had one of these years ago!
