Healthmark™ Technology
Smart Box™ uses science to tell you what your cat can’t. We developed Healthmark™ Technology to change color if any abnormalities are detected in your cat's urine. See what they can’t say.

How does it work?

Smart Box™ contains a mix of corn-fiber pellets and color-changing Healthmark™ pellets. The litter will change color if abnormalities are identified in the acidity and alkalinity levels or if blood is present in your cat’s urine.
This may indicate a serious health problem or internal injury. It is recommended you alert your cat’s vet.
It is recommended you monitor your cat and if the Healthmark™ is red-brown for more than 48 hours, consult your cat’s vet.

Abnormalities detected

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. Smart Box™. See what they can’t say.
**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.
