Abstract

A cat litter product is provided and includes manufacture primarily from modified corn starch which is processed through mash distillation. The litter product is pelletized via an extrusion technology process so as to form particles the size of wheat grain. The litter product provides, collectively, a non-toxic and naturally safe, biodegradable, odor-eliminating, scented, anti-bacterial litter that clumps in a convenient size for easy disposal and which has little dust and reduces tracking by cats.

Claims (19)

1. An animal litter consisting essentially of:

a filler selected from the group consisting of sawdust, wood shavings, and a blend of distillers dried grains and sawdust;

modified starch, wherein said combination of said filler and modified starch form particles tending to agglomerate when wetted;

yucca schidegira to inhibit urease enzyme from converting urine to ammonia, thereby neutralizing ammonia production; and

zeolite for binding ammonia and water, thereby neutralizing ammonia production and mildew formation.

2. The animal litter of claim 1 , further comprising a density increasing agent.

3. The animal litter of claim 2 , wherein said density increasing agent comprises calcium carbonate.

4. The animal litter of claim 1 , wherein said composition is extruded and pelletized to form granules.

5. The animal litter of claim 4 , wherein said granules form particles tending to self reduce in size to a size that remains acceptable for use in absorption and clumping of animal waste without further mechanical size reduction.

6. The animal litter of claim 1 , wherein said modified starch is modified to improve mixing and processing characteristics.

7. The animal litter of claim 6 , wherein said modified starch is gelatinized starch.

8. The animal litter of claim 1 , wherein said sawdust or wood shavings is selected from the group consisting of pine and cedar and a combination of said woods.

9. A method of sorbing an aqueous liquid utilizing a filler formed of wood shavings or sawdust, said method comprising the steps of:

adding modified starch such that the filler and modified starch combination form particles tending to agglomerate when wetted;

adding yucca schidegira to inhibit urease enzyme from converting urine to ammonia, thereby neutralizing ammonia production; and

adding zeolite for binding ammonia and water, thereby neutralizing ammonia production and mildew formation.

10. The method of claim 9 , further comprising the step of adding a density increasing agent.

11. The method of claim 10 , wherein said density increasing agent comprises calcium carbonate.

12. The method of claim 9 , further comprising the step of extruding and pelletizing to form granules, wherein said granules form particles tending to self reduce in size to a size that remains acceptable for use in absorption and clumping of animal waste without further mechanical size reduction.
