Is Purina Tidy Cats Free & Clean Unscented Litter Worth It?

Here's the bit the listing buries: most scented litters aren't controlling odor, they're masking it, which is why the smell always seems to sneak back through. This one skips fragrance entirely and leans on activated charcoal mixed into the clay instead. Charcoal doesn't smell nice, it doesn't smell like anything, because it works by adsorption: odor molecules physically stick to its surface and get trapped rather than floating up to your nose. That only matters, though, if the waste itself gets removed quickly, and that's where the clumping comes in. The clay forms tight, solid clumps almost immediately on contact with moisture, so you can scoop the whole thing out before bacteria have much time to break it down into the ammonia smell that builds over hours. Low dust is the quieter win here: less clay kicked into the air when you pour a fresh batch or scoop, which matters more than it sounds if the box lives somewhere with poor airflow, like a bathroom or closet. None of this depends on fragrance covering anything up, which is really the whole point of calling it Free & Clean.
