About the British Shorthair
British Shorthairs are calm, stocky cats with a tendency to gain weight. Their low activity levels mean they need careful portion control.
How many calories does a British Shorthair need?
We calculate calorie needs using the veterinary RER formula: 70 × weight(kg)⁰·⁷⁵, multiplied by a lifestyle factor of ×1.0 for a typical neutered adult British Shorthair.

Wet food vs dry food for a British Shorthair
Cats are obligate carnivores with a low thirst drive — they evolved to get most of their water from prey. Dry-only diets can lead to chronic mild dehydration, which stresses the kidneys over time. Many vets recommend that wet food make up at least 50% of a cat's diet, especially for indoor cats and those prone to urinary issues.
If feeding a mix: calculate total daily calories first, then divide between food types. For example, a 4 kg neutered British Shorthair needing 200 kcal/day could eat 100g of wet pâté (110 kcal) plus 26g of dry kibble (90 kcal).
