Khvostyk Silica gel Cat Litter Green small, 3.6 L is an absorbent cat litter with fine green granules. The bag weighs 1.35 kg. According to the manufacturer, one bag lasts about 3 weeks for one cat. The fine 0.5–2 mm granules don't prick paws — neither your cat's nor yours if you walk around barefoot.
How silica gel works
Silica gel is dried polysilicic acid gel (SiO2). Chemically it's the same substance as ordinary sand, but highly porous: its surface area is about 800 m² per gram. That's why silica gel absorbs moisture and locks in odour instantly, while never turning into a sticky mass, clinging to paws or getting tracked around the home. The manufacturer also notes that silica gel is hygienic and copes well with bacteria. The fine green granules look neat and suit both male and female cats.

- Faster use with several cats. The 3 weeks applies to one cat.
How to use it
Pour the litter into a dry, clean tray to a depth of 3–5 cm. Remove solid waste regularly and stir the litter every 1–2 days so that moisture spreads across all the granules and the litter lasts longer. At least every 3–4 weeks, replace all the litter with fresh and wash the tray. Don't flush used silica gel down the toilet, to avoid blocking the drains. If your cat is used to another litter, switch gradually by mixing silica gel into the old one.
For kittens and small pets
The manufacturer says the fine granules are harder to eat and can be used for small pets, but advises caution: eating silica gel is dangerous to health. For kittens that are just learning to use the tray and taste everything, wood or soy litter is safer — see how to litter-train a kitten and how to choose cat litter.

Who it suits
Adult cats that dislike large crystals, and owners who want a litter that controls odour and doesn't get tracked around the flat. If you need a bigger volume, see our KOTIX 10 L silica gel review. More options are in the cat litter section.
Verdict
Khvostyk Green small is a convenient fine-grain silica gel: it absorbs moisture and odour instantly, doesn't stick to or prick paws, and one bag lasts about 3 weeks. An excellent choice for an adult cat; for kittens and animals that taste their litter, a different material is better.
