The litter tray system has two sections. The upper part has a grating in the bottom.
On this grating you put ECO Kattströ up to the 2cm mark. When the cat urinates, 90% of the urine passes through the grating, falling to lower section of the tray. The rest of the cat urine is absorbed by the ECO Kattströ which is affected and falls apart into sawdust. The natural behaviour of scratching by the cat helps the sawdust to fall through the grating. You only need to throw away the sawdust that falls into the lower section. The only slight smell is of wood. No smell of cat urine can be scented. The cat’s paws are always kept dry.
