The following calculator estimates energy requirements of adult cats based on the guidelines of the European Pet Food Industry Federation (Fédération européenne de l'industrie des aliments pour animaux familiers; FEDIAF). Please note that the calculation is based on the estimated ideal bodyweight using the selected body condition score. For more information, please see the FEDIAF Nutritional Guidelines for Cats and Dogs.

Actual energy requirements may vary depending on an individual animal's clinical status, activity level, body condition and environment. This tool is not a substitute for professional clinical judgment, and users remain responsible for interpretation and application of the results.
