You can observe urine pH trends at home with color-changing litter, but an at-home color result is not the same as veterinary urinalysis. The safest approach is to use consistent conditions, record repeated results and seek veterinary care for symptoms or persistent changes.
What you need
- A clean litter box
- Fresh Purrify health-monitoring litter
- The current package color guide
- Neutral white lighting
- The Purrify app, a notebook or photographs
Step-by-step monitoring routine
- Clean and dry the box without leaving chemical residue.
- Add the recommended depth of fresh litter.
- Identify a fresh urine clump.
- Read it within the package’s recommended time.
- Compare it with the chart under neutral light.
- Record the date, time, color, appetite, water intake and behavior.
- Look for a trend over several observations.
Factors that may affect urine pH
Diet, hydration, medication, supplements, stress, timing and health may influence urine. Do not change a prescription or urinary diet based only on a home result.
How veterinary testing is different
A veterinary urine test can assess concentration, cells, blood, glucose, protein, crystals and bacteria in addition to pH. A culture may be needed to confirm infection.
When to contact a veterinarian
Contact a veterinarian for repeated unusual colors or urinary symptoms. An inability to pass urine is an emergency.

Frequently asked questions
How often should I record a result?
Record enough observations to recognize your cat’s routine without causing stress. Follow veterinary advice for cats with known urinary conditions.
Can I use the same box for two cats?
You may not know which cat produced a result. Separate boxes improve attribution.
