Pet Food Portion Calculator
Know exactly how much to put in the bowl. Convert a daily calorie target into cups or grams of your specific food, split across meals.
The gap between “a scoop” and a portion
Two foods can look identical in the bowl yet differ by hundreds of calories per cup. A performance kibble and a light formula fed “one scoop twice a day” can put a pet on opposite weight trajectories. Feeding by energy density closes that gap: you decide the calories, and the calculator translates them into your food’s own cups and grams.
Weigh dry food with a kitchen scale when you can — measuring cups vary by how you scoop, and grams are far more consistent than “about a cup.”
Frequently Asked Questions
Where do I find my food's calories per cup or per kg?
The energy density is on the packaging or the brand's website, usually written as 'ME' (metabolisable energy) in kcal/cup for dry food or kcal/kg for the overall product. If only one is printed, enter that one — the tool works from either, or both if you have them.
Why not just follow the feeding chart on the bag?
Bag charts are broad ranges built around averages and often run generous. Feeding to a calorie target that reflects your pet's actual weight, life stage, and activity is far more precise, and it accounts for treats and toppers you might add on top of the main meal.
How many meals a day should I split it into?
Most adult dogs and cats do well on two meals a day; puppies and kittens usually need three or more smaller meals. The calculator simply divides the daily amount evenly across the number of meals you enter, so you know how much to put in each bowl.
Should treats count toward the daily amount?
Yes. A good rule of thumb is to keep treats to no more than about 10% of daily calories and subtract them from the meal portions, so the extras don't quietly add up to weight gain. If you treat heavily during training, trim the meal portions to match.
My pet is gaining or losing weight on the calculated amount — what now?
Portions are a starting point, not a prescription. If body condition is drifting the wrong way, adjust the amount by around 10% and re-check in two to four weeks. If weight change is rapid, unexplained, or you're managing a health condition, talk to your vet before making bigger changes.
Educational estimate only — not veterinary advice. Read your food’s label and feed to body condition; confirm portions with your vet for pets with health conditions.
