Abstract
A pet litter composition comprises a particulate substrate having bonded onto its surfaces a fine particulate superabsorbent polymeric material and a particulate soluble polymer to promote clumping. When wetted with urine, the exposed superabsorbent and soluble polymer localise the urine and result in the rapid formation of a strong agglomerate that can easily be removed from the pet litter composition and that disintegrates when added to water.
