Has anyone else noticed that Tidy Cats keeps coming out with new formulas and then discontinuing them? It seems like I can't find the same formula more than 3 months in a row. First the Breathe Easy and Power Blend got discontinued. Then they came out with Active Spaces and Dual Power. I liked Active Spaces but they discontinued that one. Right now I like Small Spaces but I just went shopping today and there's a new formula in its place. . .4-way Power? Or something like that (looked it up; it's 4-in-1 Strength). Although on their website it appears Small Spaces is still available. I just wondered if this is nation-wide or if I live in a special experimental area :tongue2:. Every time I like a litter it gets discontinued!
