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 are formed by contact with liquids and thus absorb liquids and unpleasant odours. Clean the pile and stool daily. This keeps the litter left in the box fresher for longer. Add approximately the same amount of Biokat's litter as was removed.
