Where do I find my food's calories per cup?

It's printed on most quality dry pet food bags under 'Calorie Content' or 'Metabolizable Energy (ME)' -- typically expressed as kcal/cup and kcal/kg. If it's not on the bag, check the manufacturer's website or call their customer service line; reputable brands provide this figure readily.

Does the calculator work for wet food?

Yes, but wet food is typically expressed in kcal per can or kcal per 100 g rather than kcal per cup. Convert to kcal per cup (multiply kcal/100 g by 2.366 for a standard 8 fl oz cup) or simply use kcal per gram directly with a kitchen scale for more accuracy.

How accurate is the grams estimate?

The grams figure uses a fixed approximation of 120 g per cup -- a reasonable average for dry kibble, but actual density varies by brand and formula. For accurate gram portions, weigh your food directly on a kitchen scale rather than relying on the cup-to-gram conversion.

My pet seems hungry on the calculated portion. What should I do?

First, verify that the calories-per-cup figure is accurate for your specific food and that portions are being weighed rather than scooped. If both check out, discuss the portion with your vet -- some pets have higher individual metabolic needs than the formula predicts, and others show hunger behaviors that are behavioral rather than caloric.

Should I adjust the portion if my pet has treats?

Yes -- treat calories should come out of the daily total, not be added on top. If your pet's daily target is 500 kcal and they receive 50 kcal in treats, the main meal portion should be calculated on 450 kcal, not 500 kcal. The Treat Calculator can help you budget this clearly.

The Food Portion Calculator converts your pet's daily calorie target into a practical serving size in cups and grams, based on the calorie density of their specific food. Here's the formula and how to read the result.
