Why is this not sold any longer? I loved this stuff almost as much as the Arm&Hammer flushable (which was also taken off the market). It doesn't track off all over the place and leave me stepping on huge clumps of cat litter all over my floor in my house. I rely on flushable to help me control the catbox odor since I am allergic to most smells and fragrances. Why does the good stuff always go away?
