About the Sphynx
Sphynx cats have no fur and must maintain body heat through metabolism alone — giving them significantly higher caloric needs than most breeds.
How many calories does a Sphynx need?
We calculate calorie needs using the veterinary RER formula: 70 × weight(kg)⁰·⁷⁵, multiplied by a lifestyle factor of ×1.4 for a typical neutered adult Sphynx.
| Weight | Daily kcal (neutered adult) | Dry kibble (3,600 kcal/kg) | Wet pâté (~1,100 kcal/kg) |
|---|---|---|---|
| 3 kg | 223 kcal | 62g | 203g |
| 3.5 kg | 251 kcal | 70g | 228g |
| 4 kg | 277 kcal | 77g | 252g |
| 4.5 kg | 303 kcal | 84g | 275g |
| 5 kg | 328 kcal | 91g | 298g |
| 5.5 kg | 352 kcal | 98g | 320g |
| 6 kg | 376 kcal | 104g | 342g |
| 7 kg | 422 kcal | 117g | 383g |
Wet food vs dry food for a Sphynx
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 Sphynx needing 200 kcal/day could eat 100g of wet pâté (110 kcal) plus 26g of dry kibble (90 kcal).
