Cat Food Carbohydrate Calculator

Estimate cat food carbohydrates from the label with dry-matter and calorie estimates for comparing foods for diabetic cats.

Read the Guaranteed Analysis on the cat food label and enter the protein, fat, fiber, and moisture percentages exactly as listed. If ash is provided, or if other minerals total more than about 1%, enter that value as well. Percentages on labels are shown as minimums or maximums, but you should still enter the numbers as written.

Click Calculate to see estimated carbohydrates, dry-matter carbohydrates, and calories. If you see a negative carbohydrate value, that reflects the imprecision of the Guaranteed Analysis and generally indicates a very low-carbohydrate food rather than an error.
