What is this tool?
Many feeding guides start from resting energy requirement (RER = 70 × kg^0.75) and multiply by a life-stage or activity factor to estimate maintenance calories. This tool applies that common planning pattern, then converts daily kcal into cups/grams using the kcal-per-cup and grams-per-cup values from your pet food label.
How to use it
- Choose dog or cat and a life-stage / activity option.
- Enter weight (lb or kg).
- Enter kcal per cup and grams per cup from the food label for a portion estimate.
