Adult Cat Calorie Calculator

Introduction

Please read before using this calculator:

  • The equations used in this calorie calculator are only suitable for maintenance (adult) prepared cat food, and should not be used for home-made or other diets.
  • Any analysis of the food provided by the manufacturer will be the most accurate for that specific product. However, if the calorie content is not provided on the label or the website of the manufacturer, you can use this calculator for a good estimate of the energy content of the product. 
  • Some brands of pet food have lower feeding amounts due to the formulation of their diets and different levels of digestibility. Please contact the manufacturer for the most accurate calorie content of their product and feeding guides.
  • Using this information as a starting point, each individual cat should be fed to their ideal weight and body condition score. Regular weighing of the animal and adjusting their food to their need based on weight gain/loss, by a veterinary professional, is also critical.  
  • On this page, the term ‘calorie’ refers to kilocalorie unit of energy (symbol: kcal).

For more information and how the formulas are used in this calculator please refer to our Calorie Fact Sheet.

Energy content of your cat’s food

Your cat’s daily energy requirement (DER):

Daily Feeding Amounts:

If you feed your cat treats and snacks, please note they should not form more than 10% of the whole diet’s calorie content. This means at least 90% of calorie contribution should come from the complete cat food, and up to 10% from treats.

Pet owners are advised to use accurate kitchen scales to weight the food to the exact amount recommended by the manufacturer or their vet. Feeding based on volume or estimating the amount of food is subject to error.

Using the feeding guidelines and this calculator as a starting point, each individual cat should be fed to their ideal body condition score. PFMA body condition charts can be found on www.pfma.org.uk/pet-size-o-meter. Regular weighing of the animal and adjusting their food to their need based on weight gain/loss, by a veterinary professional, is also critical.
