See what they can’t say.

Your cat is always trying to tell you something. Too bad you’ve no idea what it is. Are they hungry? Lonely? Ranting about the neighbor’s Labrador? Or worse: not feeling great? If only you could understand their language. That would save you both so much pain, including visits to the vet. But you don’t speak cat. So we created Smart Box™. Cat litter that changes color when they’re off color. So if there’s a problem, you can act fast. Which is smart, whichever way you look at it.

Abnormalities detected


Smart Box™ is the result of relentless testing and innovation. Our revolutionary cat litter contains a mix of corn-based pellets and Healthmark™ pellets. The Healthmark™ Technology pellets will change color if abnormalities are detected in the pH levels (or if blood is present) in your cats urine. Meaning if there is an issue, you can act fast.

**Smart Box™ Litter is safe to flush through residential, non-septic sewage systems designed and maintained in accordance with plumbing codes. To ensure compatibility do not flush more than one clump at a time. Local regulations on flushing vary; please ensure you comply with them. The State of California encourages the disposal of cat feces in the trash and discourages flushing feces in toilets or disposing of them in drains.
