Why it matters

Care Alert is a non-clumping silica crystal litter with pH detection technology that changes color to help you monitor your cat's health. A color change is a reason to talk to your vet.

The crystals give long-lasting ammonia odor control, and the low-dust, lightweight formula needs no clumps removed.

Who it's for, and who should skip it

Good fit if

  • Owners watching urinary health
  • Single cats
  • Low-dust homes

Look elsewhere if

  • Clumping-only self-cleaning boxes
  • Owners who want clumps
  • Multi-cat boxes

Pros and cons

Pros

  • pH indicator
  • Low dust
  • Light

Cons

  • Not a diagnosis
  • Non-clumping
  • Hard to attribute in multi-cat boxes

Limitations to weigh

  • Crystal litter suits crystal-tray boxes such as the ScoopFree and boxes whose maker lists crystal litter; most clumping-only globes reject it.
  • A color change means call your vet; it isn't a diagnosis.
