Abstract
There is disclosed an animal litter composition comprising 1) a particulate, water absorbent clayey component, e.g., sodium bentonite, containing at least one water-swellable clay mineral, e.g. montmorillonite; 2) a water-soluble salt, e.g., a sodium salt of a carboxymethylcellulose; and optionally (3) a solid particulate deodorizing additive component comprising sodium bicarbonate (SBC) or potassium bicarbonate (KBC), the particles of which are substantially coated with a mineral oil, mixed with a powdered siliceous material, e.g., expanded perlite, having a bulk density significantly lower than the density of SBC or KBC, the coated particles of SBC or KBC being stably adhered to and agglomerated with the particles of the siliceous material. On contact with a waste aqueous liquid such as urine, the litter composition forms clumps which can be easily removed from the remainder of the litter and can be disposed of with relatively little disintegration.
