The best cat litters in the UK
1. Ever Clean Extra Strong Clumping, unscented: best clay litter
A clay litter that forms hard clumps, so you lift out the wet litter and leave the rest. Choose the unscented version: cats have much better noses than we do, and a heavily perfumed tray can put some of them off. Clay litter sticks to paws, so pair it with a litter mat.
2. Catsan Natural: best plant-based clumping litter
Catsan makes it from a by-product of wheat milling and describes it as fully biodegradable. It clumps, it is much lighter to carry than clay, and Catsan is stocked by most big UK pet retailers, so it is an easy first try if you want to move away from clay. Catit Go Natural pea husk litter, £16 a bag from Catit UK, is a similar alternative.
3. Tigerino Crystals: best for smell
Silica crystals soak up urine and hold the smell in, so you scoop solids daily, stir the rest, and change the whole tray every few weeks rather than scooping wet clumps. That suits a tray that lives in a flat's living space. The crystals are not biodegradable, and some cats dislike the hard feel underfoot, so buy one bag before a multi-pack.
4. World's Best Cat Litter: best for several cats
A clumping litter made from corn, with tight clumps that are easy to lift even in a busy tray. It is expensive per bag, but because you only remove the clumps, a bag goes further than the price suggests. The Multiple Cat version is the one to buy for two or more cats sharing trays.
5. Breeder Celect: cheapest, very low dust
Paper pellets are soft, absorbent and very low in dust, which is why they are often used after surgery or for a cat with a cough. They do little for smell and do not clump, so you change the tray more often. At about 50p a litre it is still the cheapest litter here.
What cat litter is best for smell?
Silica crystals hold smell longest between changes, followed by a good clumping litter scooped every day.
Most tray smell comes from urine left sitting in the litter. Crystals absorb it and lock it in; clumping litters seal it into a clump that you remove. Paper and non-clumping litters let it soak through to the bottom, which is why they smell sooner. Scented litter only covers the smell, and it can put a cat off the tray. Keeping the tray clean does more than any brand: scoop daily and wash the tray itself when you change the litter.
Which cat litter do cats prefer?
Many cats prefer a fine, soft, unscented litter that feels like sand, but it varies, and the litter your cat already uses is the safest choice.
PDSA notes that some cats prefer a gravel-style litter and others a clumping sand style, and that some litters are uncomfortable on paws. If your cat starts going beside the tray after a change, the litter is the first suspect. To switch, mix the new litter into the old a quarter at a time over a week or two.
Which cat litter is best for kittens?
The litter the kitten used before it came home is the best start, and if you do not know it, an unscented, low-dust litter such as paper pellets or a plant-based litter.
Ask the breeder or rescue which litter the kitten is used to and keep to it for the first few weeks. Once the kitten is using the tray reliably you can move it on to whatever you want to use long term.
Which cat litter is best for the environment?
Plant-based litters such as wood, wheat, corn, pea husk and recycled paper, because they come from renewable or waste material and break down; clay and silica are mined and go to landfill.
Bentonite clay is strip-mined and silica is manufactured, and neither breaks down. Plant litters are lighter to transport too. The used litter still counts: cat faeces can carry toxoplasma, so do not put used litter on compost for food crops.
Is cat litter flushable?
Clay and silica litter are not: clay swells and can block pipes. Some plant-based litters are sold as flushable, but bagging and binning is the safer habit.
Check the bag, and your water company's advice, before flushing any litter. Cat faeces can carry the toxoplasma parasite, which is one reason not to send it down the toilet.
How often should you change cat litter?
Scoop clumps and solids every day, and empty, wash and refill the whole tray every one to two weeks for clumping litter, or when the crystals or pellets are saturated.
Non-clumping and paper litters need a full change every few days, because the urine stays in the tray. Silica crystals last the longest, often a few weeks for one cat. PDSA points out that cats will not use a dirty tray, and recommends at least two trays even for one cat.
Is cat litter safe when you're pregnant?
The litter itself is not the problem; cat faeces in it can carry toxoplasmosis, so the NHS advises pregnant women to avoid cat litter if they can, or wear gloves and wash their hands.
If someone else in the house can do the tray, let them. The NHS toxoplasmosis page has the full advice.
