Cats were fed purified diets containing varying levels of calcium pantothenate. In pantothenic acid-deficient cats the most prominent changes were growth failure and histologic changes in the small intestines and the liver. The results of gross and histologic examinations, measurements of acetylation of urinary p-aminobenzoic and the ratio of urinary pantothenic acid to creatinine indicate that in this study, cats required approximately 5 mg of calcium pantothenate/kg of diet.
