Orientative food grams, kcal and water by weight, stage and activity. Rabbit notes (hay, pellets) included. Does not replace the bag label or a vet.
Orientative portion / day
0 g
≈ 720 kcal (average dry food)
Spread over 2 meals: about 100 g each
Based on average dry kibble. Adjust with your vet for brand and real body condition.
Orientative water / day
0 ml
Baseline maintenance need (MSD Veterinary Manual). Actual drinking varies with diet (dry or wet food), heat and exercise. Always keep fresh water available.
Daily energy need = resting energy (70 × body weight in kg to the power 0.75) × a life-stage factor, for example 1.6 for a neutered adult dog or 1.2 for a neutered adult cat. We then convert calories to grams using 3.6 kcal per gram, a typical value for dry food. Check your food's label: energy per gram varies by brand.
These are starting estimates. Individual animals can differ by up to 50%, so adjust to body condition with your vet.

Guides
This tool combines weight, life stage, activity and diet type to provide a daily reference. It is designed to help you start with a sensible amount and then adjust over time using body condition, energy and the food maker’s guidance.
How to read the result
We start with an orientative energy estimate and convert it into an approximate daily amount for the selected diet. We do not treat the number as a prescription: foods have different calorie densities, and two animals at the same weight can need different amounts.
The result does not replace veterinary advice or a body-condition assessment. Puppies, seniors and animals with medical conditions can have rapidly changing needs.
How to use it well
Does it replace a vet? Are portions exact? Other species?
Guidance only. Does not replace a licensed veterinarian. In emergencies, go to a veterinary clinic.
