Purrify Health Monitoring Cat Litter
Purrify makes one product: a plant-based clumping cat litter with a urine pH indicator built into the pellets. When a cat wees, the clump changes colour across a pH 4–10 scale, and the free purrify App lets you photograph the clump, record an estimated reading and follow the trend for each cat in the house. The litter itself is made from pea fibre, corn starch and cassava starch in dense 1.5mm pellets — low dust, unscented and fast clumping.
Who it suits
It makes most sense for a cat that has had crystals, a blocked bladder or recurrent urinary trouble, or for an older cat where you want an easy daily check. Urine pH changes with diet, water intake and time since the last meal, so read it as a pattern rather than a single result: one odd-coloured clump is normal variation, a shift that holds for several days is worth a conversation with your vet. Purrify is an observation tool and does not replace a urine test.
Getting a clear reading
Use it on its own in a clean, dry tray — mixed into another litter, the colour is diluted and hard to judge. When switching over, blend it into the old litter gradually across a week or so; it is unscented, which some cats used to a perfumed litter take a little while to accept. A 4.54kg bag lasts about a month for one cat; the 3-bag pack is the better value for multi-cat homes.
