CSI URINE Litter Granules are a litter tray additive designed to extend the usable life of cat litter by tackling urine odour at the source. They're added on top of existing litter rather than replacing it, and are suitable for any litter tray setup across single-cat or multi-cat households.

The granules use bio-active enzymes that break down urine at a molecular level rather than simply covering the smell with fragrance. The product contains no masking deodorisers, which matters for cats that are sensitive to perfumed litters and will sometimes reject the tray because of added scents. In practice, the granules extend the time between full litter changes, which reduces both the waste going to landfill and the ongoing cost of topping up the tray.

Litter additives like CSI URINE Granules are a low-effort win for households where tray smell is becoming an issue between changes, particularly in warmer months. CSI's broader range also includes an enzymatic tray cleaner for full resets, so the granules slot naturally into a full litter-hygiene routine.
