About the Siamese
Siamese cats are lean, vocal, and very active. They have higher metabolic rates than many breeds and benefit from slightly higher calorie targets.
How many calories does a Siamese need?
We calculate calorie needs using the veterinary RER formula: 70 × weight(kg)⁰·⁷⁵, multiplied by a lifestyle factor of ×1.3 for a typical neutered adult Siamese.
| Weight | Daily kcal (neutered adult) | Dry kibble (3,600 kcal/kg) | Wet pâté (~1,100 kcal/kg) |
|---|---|---|---|
| 3 kg | 207 kcal | 58g | 189g |
| 3.5 kg | 233 kcal | 65g | 212g |
| 4 kg | 257 kcal | 71g | 234g |
| 4.5 kg | 281 kcal | 78g | 256g |
| 5 kg | 304 kcal | 85g | 277g |
| 5.5 kg | 327 kcal | 91g | 297g |
| 6 kg | 349 kcal | 97g | 317g |
| 7 kg | 392 kcal | 109g | 356g |
Wet food vs dry food for a Siamese
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 Siamese needing 200 kcal/day could eat 100g of wet pâté (110 kcal) plus 26g of dry kibble (90 kcal).
