AnimAll Green Emerald, 10.5 l is an unscented silica gel cat litter with green crystals from AnimAll International GmbH. Silica gel is dried polysilicic acid gel (SiO₂), chemically the same as sand but highly porous: one gram has a surface area of up to 800 m². That's why it instantly absorbs moisture and odour, never turns into a sticky mass and doesn't cling to paws. The 10.5 l bag weighs 4.4 kg and has a carry handle and a zip-lock that keeps the litter dry once opened.
How silica gel works
The porous crystals absorb liquid, and odour is trapped in the pores. Unlike clumping bentonite, silica gel doesn't form clumps: urine is absorbed by the crystals and the tray stays dry. So you only scoop solids regularly, stir the litter and replace it entirely every few weeks. More on litter types in how to choose cat litter.

Pros

- Doesn't stick to paws. Less tracking around the home.
- Unscented. Suits scent-sensitive cats.
- Economical size. 10.5 l is better value than small bags.
- Zip-lock. Stays dry after opening.
- Lightweight. Lighter than the same volume of bentonite.
Cons
- Non-clumping. Urine can't be removed separately — the whole lot is replaced.

- The crystals crunch. Some cats dislike the texture.
- Kittens may taste it. Keep an eye on little ones.
How to use it
Pour the litter into a clean, dry tray to a depth of 3–5 cm. Remove solids regularly and stir every 1–2 days so damp crystals are spread evenly. Replace all the litter and wash the tray at least every 4 weeks. According to the manufacturer, a 3.8 l bag lasts one cat about a month, so 10.5 l lasts longer or covers several cats. Bin used silica gel rather than flushing it — more in can you flush cat litter.
Switching your cat to silica gel
Cats are creatures of habit, and a sudden litter change can lead to accidents. Mix silica gel with the old litter for a week, gradually increasing the share of the new one. If your cat still refuses, check whether it likes the tray and whether the tray is somewhere noisy. More in cat not using the litter tray: what to do.
Silica gel, bentonite or tofu
Silica gel controls odour best and rarely needs a full change. Bentonite is cheaper and clumps, while tofu can be flushed. Compare with the bentonite Van Cat Vanilla and silica gels KOTIX 10 l and AnimAll Amethyst Crystals.
Which tray suits it
An ordinary tray without a grid works for silica gel. A covered tray reduces scattering, and a mat at the exit catches crystals from paws. On choosing a tray, see which litter tray to choose for your cat.
Storage
Keep the bag zipped shut in a dry place: silica gel absorbs moisture from the air and loses its properties faster in damp rooms.
Who it suits
Cat owners who value odour control and infrequent changes, and multi-cat homes. More options are in the silica gel litter collection and the cat litter section.
Verdict
AnimAll Green Emerald 10.5 l is an unscented silica gel litter that instantly absorbs moisture and odour, doesn't stick to paws and is good value in a large zip-lock bag. The downsides are that it doesn't clump, can't be flushed, and not every cat likes the crunchy crystals.
