Abstract

A method is provided for reducing stool odor of a companion animal such as a cat or dog. The method comprises causing the animal to ingest a composition comprising a stool odor reducing effective amount of a zinc ion source, for example zinc acetate.

Claims

1. A method for reducing stool odor of a companion animal in need thereof, the method comprising causing the animal to ingest a pet food composition consisting of:

(i) a stool odor reducing effective amount of a zinc ion source;

(ii) about 5% to about 45% by weight carbohydrate based on the weight of the composition;

(iii) about 10% to about 60% by weight protein based on the weight of the composition;

(iv) about 5% to about 40% by weight fat based on the weight of the composition;

(v) about 0.1% to about 20% total dietary fiber based on the weight of the composition; and

(vi) 0 to about 15% nutritional balancing agents based on the weight of the composition.

2. The method of claim 1, wherein the zinc ion source is present in the composition in an amount providing about 75 ppm zinc ion and not sufficient to cause an adverse effect on digestion of the animal.

3. The method of claim 1, wherein the zinc ion source is present in the composition in an amount providing about 75 ppm to about 3000 ppm zinc ion.

4. The method of claim 1, wherein the zinc ion source is a zinc salt.

5. The method of claim 4, wherein the zinc salt is selected from the group consisting of zinc acetate, zinc citrate, zinc gluconate, zinc ascorbate, zinc glycinate, zinc sulfate, and sodium zinc citrate.

6. The method of claim 4, wherein the zinc salt is zinc acetate.

7. The method of claim 6, wherein the zinc acetate is present in the composition in an amount providing about 200 ppm zinc ion.

8. The method of claim 6, wherein the zinc acetate is present in the composition in an amount providing about 500 ppm zinc ion.

9. The method of claim 1, wherein the animal is a cat.

10. The method of claim 1, wherein the animal is a dog.

11. The method of claim 1, wherein the composition is in the form of a toy coating.

12. The method of claim 1, wherein the composition is in the form of a pill, a tablet, a gel or a capsule.
