Smart Box is a sustainable health monitoring cat litter that uses Healthmark Technology to tell you what your cat can't. The cat litter will change colour if abnormalities are detected in your cats urine, allowing you to act fast if there is an issue. Smart Box contains a mix of corn-fiber pellets and colour-changing Healthmark pellets. One 6lb box of our lightweight clumping litter lasts up to 1 month and is 99.9% dust-free, low tracking and has up to 30 days of odour control. Derived from corn, our flushable* natural litter pellets are a sustainable alternative to crystal or clay litters without sacrificing performance.

Smart Box is safe to ?ush through residential, non-septic sewage systems designed and maintained in accordance with plumbing codes. To ensure compatibility do not ?ush more than one clump at a time. Local regulations on ?ushing vary; please ensure you comply with them.
