Add granules to any single colored litter and if your cat's urine is above (acid) or below (alkaline) the pH of normal cat urine, granules change color - yellow for acidic urine and purple for alkaline urine.
Cats may not show they don't feel their best, and monitoring your cat's urinary pH can help when you suspect he doesn't feel well. Litter additive changes color when cat urine is acidic or alkaline, so you may be able to schedule a veterinary visit before outward signs of illness appear. Safe for pets.
