Biokat's ORGANIC is made of 100% natural, untreated plant fibres which come from sustainable European sources. ORGANIC is a particularly effective cat litter, as the plant fibres are extremely absorbent. On a day to day basis, you only need to remove the lumps, so the residual filling of the litter can stay in the cat litter tray for at least 4 to 6 weeks. You can find details of how long this bag will last on the front of the bag. Unpleasant odours are quickly absorbed thanks to the special tubular structure of our plant fibres. This suppresses odours for a long time. Up to 700% absorbency, ORGANIC is a natural clumping litter made from particularly absorbent plant fibres which act like a sponge. They absorb liquids completely. Lumps are formed which lock in the liquid as well as the odour. Easy to carry, our plant fibres weigh up to 70% less than comparable cat litter made out of natural clay. This makes them particularly easy to carry. Single clumps can be disposed of easily and hygienically! Put lumps into the toilet one at a time. Let them dissolve and flush. The rest of the cat litter can be disposed of in compost or organic waste. When doing so, please adhere to local regulations. 100% bio-degradable. Our fibres are suitable for compost.This makes our litter much better for the environment!
