Nutrient guidelines based on AAFCO growth and reproduction profiles for cat foods. 2Felids must have a dietary source of preformed vitamin A since they are unable to convert carotenes (vitamin A precursors) to retinol (vitamin A). 3Add 10 IU of vitamin E above minimum level per gram of fish oil per kilogram of diet.
