PrettyLitter Health Monitoring Cat Litter
Last updated: 19 October 2026
PrettyLitter is a silica crystal cat litter that changes colour with the pH of your cat's urine, so you get an early hint that something might be wrong. It is non-clumping, unscented and light to carry. PrettyLitter used to be US-only, but Amazon UK now sells the 6lb bag for £33.37, shipped from Amazon US.

What PrettyLitter is
Most cat litter is clay that clumps when wet. PrettyLitter is different: it is made of silica gel crystals that soak up urine and lock in the smell, so there are no clumps to scoop out.
The trick is in the colour. The crystals react to the pH of the urine and change colour, which can point to problems such as a urinary tract infection, bladder inflammation or kidney stones. As a result, you may spot a change before your cat shows any other sign.
What it does
- Colour change: the crystals change colour depending on the pH of your cat's urine.
- Odour control: the silica soaks up liquid and holds the smell, and the bag is unscented.
- No scooping clumps: it does not clump, so you remove solids and stir the rest.
- Light to carry: a 6lb bag weighs about 2.7kg.
- Fits most trays: it works in standard, disposable and many automatic litter trays.

The limits
PrettyLitter is a warning light, not a diagnosis. A colour change tells you to see a vet, and a normal colour does not mean your cat is well. PDSA's guide to urine problems in cats lists the signs to watch for. It also warns that a cat straining with no urine is an emergency, which is "most common in males and often fatal if not treated quickly".
Multi-cat homes make the colour harder to read, because you cannot tell which cat used the tray.
It costs more than clay. At £33.37 a bag for one cat for up to a month, it is dearer than most UK litters, and it ships from the US.
Finally, some cats dislike the feel of crystals. Mix it with their old litter for a week or two before you switch fully.
Where to buy PrettyLitter in the UK
PrettyLitter has no UK shop of its own. Amazon UK sells the 6lb unscented bag, sold and shipped by Amazon US, with Amazon's usual 30-day returns.
