<p>The composition of ultra light litter of small animals comprises multivalent acidically hydrolyzing metal sulfates such as iron/aluminum sulfates, alums, sodium bisulfate/trisodium bisulfate, water soluble solid organic acids or acid anhydrides maleic acid anhydride, and an additive (1-5%) in a form of solid state that is soluble in water with acidic effect. The compositions are constituted by mixtures of gypsum/cement (30-60%), expanded up punvicit/perlite (10-50%), and starch/flour/carboxymethyl- or hydroxyalkyl-cellulose derivates (0.5-40%) modified by hot water/base treatment.

The granule is composed of the compositions or two(multi) layered having a light, solid inner core, which is a foamed, burnt clay granule and an active layer composed of the compositions. The mixture has a bulk density of 0.2-1.2 g/cm3>.</p> |
