All Purina Cat Chow brand cat foods are formulated to contain different levels of protein dependent upon the product and the life stage the product is intended for. Purina Kitten Chow brand kitten food contains the highest level of protein because it is a diet intended for growing kittens as well as adult cats at maintenance and female cats during pregnancy and lactation. Kitten Chow also contains a higher level of fat since kittens require more energy during the growth portion of life. Purina Cat Chow Original Formula brand cat food is also complete and balanced for all life stages but it contains lower levels of protein and fat as compared to Kitten Chow. Purina Cat Chow Indoor Formula and Purina Cat Chow Vitality Formula contain similar levels of protein but lower levels of fat as compared to Cat Chow Original Formula since older, less active cats require less energy than active adult cats.
The guaranteed analysis on a pet food label can be used to give an estimate of the carbohydrate level of a dry cat food. To calculate the carbohydrate percentage you would take 100% and subtract the % Moisture, % Protein, % Fat, % Ash, and % Fiber. The remaining percent is the estimate of the carbohydrate in the diet. Although the numbers provided in the guarantees are minimums and maximums, you still should be able to calculate an approximate level of carbohydrate since the minimums and maximums are usually fairly close to the level actually present in the food. If the guarantees are not listed for the above nutrients, you usually can get a typical analysis for most pet foods by checking the website for the manufacturer of the food.
