Sepiolite is a porous clay litter with absorbent properties, which is used as a litter for cats to defecate and urinate on. The problem is that when used in the cage tray, every time the parrot flaps its wings, it will raise dust and breathe it involuntarily, which can cause respiratory diseases or become a source of respiratory and eye irritation. The best bedding for the cage is Bird Litter: a litter based on crushed corn cob.
