Locks odours in at the source
Pacha's silica gel crystals trap ammonia and odour molecules deep in their micropores and absorb up to almost 50% moreiOur in-house lab water-absorption testWe saturate the litter with water and measure how much it holds, as a percentage of its own weight.
For 100 g of litter:
• Ordinary silica: holds ≈ 153 g of water (153.21%)
• Pacha litter: holds up to ≈ 224 g of water (224.48%)

- One scoop is enough
- Traps odours deep down
- No added fragrance
A 45-second-a-day routine

- No need to remove the urine
- One tray clean a month
Keep an eye on your cat's health
Cats hide pain on instinct, by the time the signs show, it's often too late. Pacha's crystals change colour on contact with urine to alert you before symptoms appear.

Already spotted an issue with one of my cats.
Virtually dust-free
The dust that puffs up when your cat scratches is what they breathe in, and you too. Pacha uses a patented filtration technology, developed with vets, to hold back almost all of it.
- Dust-free pour
- Kinder to the airways
- Doesn't stick to paws
One bag lasts a whole month
One 2.7 kg bag of Pacha replaces up to 4 bags of standard clumping litter. Because it doesn't clump, the crystals soak up the urine all month: one bag lasts a whole month for one cat.
- Replaces 4 standard bags
- Works out cheaper
- Just one light 2.7 kg bag

Why Pacha?
Pacha was created with vets and cat owners, around a brief short enough to fit on one line: a tray that stays dry from the first day of the month to the last.
The smell in the tray comes from urine breaking down and releasing ammonia. A fragrance doesn't change that reaction. It just puts a layer over the top, and after a few days the ammonia comes through again. That's why our bags don't have any.
The crystals themselves are riddled with micropores, a sort of mineral sponge. Moisture and odour molecules go in and stay in, so the tray stays dry and nothing drifts back into the room.
Those same crystals react to the acidity of the urine and shift colour. So each day you get a quick read on how your cat is doing. It's a cue, not a diagnosis: if the colour changes, speak to your vet.
Beyond that: 4.6/5 on Trustpilot, a subscription you can stop whenever you like, and a 30-day money-back guarantee. If it isn't right for you, you keep the litter and there's nothing to send back.

Still got a question?
Does it smell after a month?
With Pacha, you only scoop the solids and leave the urine in the tray. It can sound surprising, but that's the whole point of the refined silica crystals: stir the litter every day (45 seconds) and the urine and its odours are soaked up and dried out continuously inside them.
Because no moisture sits around, bacteria find it far harder to grow, and your cat walks on dry litter.
Is silica dangerous for my cat?
You may have heard warnings about certain types of silica. They aren't the silica crystal Pacha litter is made of.
Pacha is a patented formula, developed with vets: no added fragrance, no chemical additives, and refined granules that barely stick to paws.
Does it work out more expensive?
A bag of standard supermarket litter costs around £5–£8iStandard 10L supermarket bagsStandard clumping litter, 10L bags, sold in supermarkets and pet shops.
Indicative prices for 2025–2026; they vary by retailer and by offer., and you go through 3–4 a monthiSourcesASPCA, "Completely replace the litter once a week."
Dr Louise Barnes, MRCVS (Cats.com), "Non-clumping litter should be emptied at least once a week.". That works out at roughly £15–£32 a month.
Pacha is £21 a month for one cat, delivery included. So the budget is much the same, with one light bag delivered to your door instead of several heavy ones to carry, plus a colour that gives you a daily cue about your cat's urinary health.
How long am I tied in for?
Pacha litter comes as a monthly subscription with no commitment.
You choose how many cats, get your litter delivered free every month, and can change or cancel your subscription any time, in 30 seconds.
