I'm surprised you had a problem because that's the litter I use and it clumps just fine. And actually, I've tried to "unclump" it because we like to spread some around outside by where we park the motorhome to keep mice away, and it's the grossest thing trying to break apart these sticky gooey clumps of cat pee. Eeewwww Terry's like "just spread it around." I'm like "It doesn't spread, you wanna try!"

Maybe it was just a bad batch or something, but I'm surprised. They also make another brand that's "continuous odor control" (red label) that I bought this time because they were out of the regular "blue" stuff that I buy. This continuous odor control stuff obviously has a lot of perfume in it - bothers my nose when I scoop it so I can't imagine how T & P tolerate it. Although I gotta admit there's no "cat litter odor" just an overwhelming obnoxious perfume odor.
