Purrify is a plant-based clumping cat litter with a urine pH indicator built into the pellets. When your cat wees, the clump changes colour, so you can see roughly where their urine pH sits each time you scoop — no test strips, no extra step. It suits owners who want an easy daily check on a cat with a history of urinary trouble, or who simply want to notice changes early. It is an observation tool, not a diagnosis: urine pH moves with diet, water intake and time of day, so a single odd-coloured clump means little on its own. What matters is a shift that persists over several days.
Each bag is 4.54kg, about a month's supply for one cat. The 3-bag pack ships in a single carton. Browse the rest of our cat litter range or other plant-based tofu litters.
Benefits
- Smart pH Insight — the clump shows a colour response across pH 4.0–10.0, from pink-orange (acidic) through pale yellow-green (normal) to teal (alkaline)
- Free purrify App — photograph a coloured clump to record an estimated pH, keep a profile for each cat and review the trend over weeks
- Firm, fast clumps — locks moisture on contact into solid clumps that lift out without crumbling or sticking to the tray
- Low dust, unscented — dense 1.5mm pellets made from pea fibre, corn starch and cassava starch
- All life stages — suitable for kittens, adult and senior cats
- Paper packaging — FSC-certified paper-based bag
Reading the Colours
- Acidic, pH 4.0–5.4 — strongly acidic urine; persistent readings here are associated with calcium oxalate crystal risk in susceptible cats
- Slightly acidic, pH 5.5–5.9 — commonly seen in healthy cats; keep watching the pattern
- Normal, pH 6.0–7.5 — broadly consistent with typical feline urine
- Slightly alkaline, pH 7.6–8.4 — can rise briefly after meals; a persistent reading can favour struvite crystals
- High alkaline, pH 8.5–10.0 — markedly alkaline; persistent readings warrant a vet check
Ingredients
Pea residue, corn starch, guar gum, antimicrobial agent, pH indicator.
How to Use
Fill a clean, dry tray to a depth of 5–8cm and use Purrify on its own — mixing it with another litter dilutes the colour and makes readings hard to judge. For the most accurate reading, check the clump colour within an hour of your cat using the tray, compare it with the colour guide on the bag, and log it in the app if you want to track a trend. Scoop clumps daily. Switching from a different litter? Blend it in gradually over a week or so; Purrify is unscented, which some cats used to a perfumed litter take a few days to accept.
Smart pH Insight is for everyday wellness observation only. It does not diagnose, prevent or treat any medical condition and is not a substitute for veterinary advice. If readings stay outside the normal range, or your cat is straining, urinating often, passing small amounts or showing other unusual litter-box behaviour, see your vet promptly.
