PrettyLitter Health Monitoring Cat Litter is a veterinarian-developed silica crystal litter designed to do more than manage odor — it actively monitors your cat's urinary health. The color-changing crystals shift hues to indicate changes in urine acidity, alkalinity, or the presence of blood, which may be associated with conditions such as urinary tract infections, bladder inflammation, urinary stones, or blood in the urine. This Costco value pack includes two 8 lb bags for a total of 16 lbs, providing up to four months of litter supply for a single cat.

Unlike traditional clumping clay litters, PrettyLitter's non-clumping crystals absorb liquid on contact and trap moisture inside, so routine maintenance requires only scooping solid waste. The ultra-lightweight formula produces significantly less dust than clay litters and eliminates the heavy, messy clumps associated with conventional options. The litter is formulated for both single- and multi-cat households and features an odor seal guarantee, keeping the litter box area fresher for longer with less frequent full changes. PrettyLitter lasts up to twice as long as clumping clay litter by volume.
