The most important market for absorbent clays such as sepiolite, bentonite, attapulgite is cat litter.
The most important characteristics of the clay to be used in this sector are absorption rate, bulk density, and the size of the granules. The absorption capacity of the clay to be used should be high and its granule size should be 1 – 6 mm. The clays used as cat litter are divided into two as heavy clays(Bentonite) and light clays (Sepiolite, Attapulgite). Light clays have the 70% of the european cat litter market.
