Classic and natural litter is often the favourite of many felines and is also the cheapest litter on the market. It is noted for its great absorption power and does not contain perfumes or other additives. It is made with sepiolite, a very porous mineral that will soak up liquids, keeping the rest of the litter box dry. It is also a very light type of litter, so your feline will be able to hide its faeces without any problems.
