About this tool

Feeding guides on the bag are averages written for an animal that may look nothing like yours. The standard approach is to start from resting energy requirement — roughly 70 × (body weight in kg)^0.75 — then multiply by a factor for life stage, neuter status and activity. That gives a daily calorie target, which you divide by the calorie density on your food's label to get grams. This tool does that calculation and lets you enter your own food's kcal per cup or per 100 g. It is a starting point: body condition score and your vet's advice beat any formula.
