Abstract

Abstract A cat food composition of improved acceptability to cats is provided as well as a process for generally enhancing the palatability of dried or intermediate moisture cat foods wherein the cat food composition is coated with a synergistically effective flavor enhancing mixture comprising between about 87 to 13 parts by weight of phosphoric acid to 1 part by weight of citric acid wherein said coating is applied on the composition to provide a level of phosphoric acid in the cat food product of at least about 0.5% by weight. Cat food compositions containing the synergistically effective coating are significantly more palatable to cats than compositions which contain only citric or phosphoric acid as palatability enhancers.
