Chromogenic Absorbent Material for Animal Litter

A chromogenic absorbent material for hemoglobin and/or glucose detection in an animal excretion, the chromogenic absorbent material comprising:

• a benzidine-type compound;
• at least one of:
• an organic hydroperoxide, for catalyzing the oxidation of the benzidine-type compound in the presence of hemoglobin;
• and
• a catalytic system comprising:
• a first enzyme which is an oxidoreductase, for in situ generation of hydrogen peroxide in the presence of glucose;
• and
• a second enzyme which is a peroxidase, a pseudoperoxidase or a combination thereof, for catalyzing the oxidation of the benzidine-type compound upon in situ generation of the hydrogen peroxide;
• a salt of alkylbenzene sulfonate;
• and
• a polysaccharide matrix comprising a chemically or mechanically processed non-functionalized cellulose and pregelatinized starch (PGS).
