Abstract: Zeolite is added to animal food compositions in amounts sufficient to enhance palatability, preferably in amounts of from about 0.01% to about 4% by weight of the composition. The compositions containing zeolite are ingested more frequently and at a higher rate by animals, particularly finicky animals or older animals that tend not to eat enough food to maintain their health.

Abstract: Methods for enhancing the palatability of compositions for consumption by an animal by adding a palatability enhancing amount of at least one methionine compound and optional inactive yeast to the compositions. The methionine compound, and optional yeast, is added to the compositions in an amount of at least about 0.01% by weight of the composition on a dry matter basis, generally in amounts of from about 0.01% to about 1.5% by weight of the composition. The compositions containing methionine compound, and optional yeast, are ingested more frequently and at a higher rate by animals, particularly finicky animals or older animals that tend not eat enough food to maintain their health.

Abstract: Methods for reducing food intake by and controlling the weight of an animal by feeding the animal a composition comprising a food intake reducing amount or a weight controlling amount of a soluble fiber.

Abstract: A method for improving stool quality by administering to an animal a composition comprising from about 1% to about 20% zeolite. Preferably, the zeolite is fed to ah animal as part of a food composition containing least one ingredient suitable for consumption by an animal.
