Cat litter is pleasant and safe for humans and cats, made of 100% natural clay. The filler is very economical, requiring smaller quantities than other types of fillers. The clumps form on contact with the liquid and thus absorb liquids and unpleasant odours. Clean out the clumps and faeces daily. This keeps the litter left in the box fresher for longer. Add approximately the same amount of Biokat's litter as was removed.
