Abstract: The clumping ability of a poorly clumping earth is augmented by mixing the earth with a water soluble or dispersible gum selected from the galactomannan gums, e.g. guar gum or derivatives thereof and provides a useful animal litter. Preferably the earth and the gum are dry mixed. Acceptable clumping performance may be achieved using as little as 0.05% of the polysaccharide by dry weight of the earth.
