Color Reference Guide
Your cat’s litter colour can offer simple daily insights into urinary wellness.
Use this guide to understand what each colour generally indicates.
According to guidelines from leading U.S. veterinary associations (AAHA / AVMA), Purrify pH Insight Cat Litter accurately measures
pH 4.0–10.0 and displays results through 7 distinct color indicators for easy understanding.
Purrify colour indicators support awareness, not diagnosis. Please consult your vet for medical concerns.
Daily Monitoring
A simple routine helps you recognise early changes and maintain your cat’s urinary wellness.
What to observe daily
Colour – Check if today’s colour differs from usual.
Clump Size – Too small may indicate low hydration; too large may reflect increased intake.
Odour – Sudden strong odour may signal imbalance.
Best monitoring practices
Check colour under natural or consistent lighting.
Scoop regularly to avoid colour mixing.
For multi-cat homes, use separate zones or observe cats individually.
When to pay extra attention
Colour stays yellow or orange for 2–3 consecutive days.
Noticeable decrease in water intake.
Significant reduction in urine volume.
Diet & Hydration Tips
Daily urinary pH changes are often linked to hydration and diet. These simple practices can help maintain balance:
Hydration Matters
Adequate water intake can:
Support ideal urinary pH
Reduce mineral build-up
Lower irritation risks
Improve urination frequency
Ways to improve hydration:
Provide multiple water stations
Use a water fountain
Mix 20–50% wet food
Offer pet-safe broth
Diet Influences pH
High-protein diets may mildly acidify urine
Alkaline-forming ingredients may raise pH
Treats should be moderate
What to do when colour shifts?
If slightly acidic/alkaline
Increase hydration and observe 1–2 days
If trends persist
Review diet
If strongly abnormal
Seek vet advice
