Cat feeding by weight
Last updated: November 3, 2026
A quick reference of estimated daily calories for common adult cat weights. The low end assumes a less active or weight-loss-prone cat (×1 RER); the high end assumes an active cat (×1.6 RER). Most typical adults fall somewhere in between.
| Body weight | Estimated daily calories |
|---|---|
| 6 lb (2.7 kg) | 148–237 kcal/day |
| 8 lb (3.6 kg) | 184–294 kcal/day |
| 10 lb (4.5 kg) | 218–348 kcal/day |
| 12 lb (5.4 kg) | 249–399 kcal/day |
| 15 lb (6.8 kg) | 295–472 kcal/day |
These are estimates only. Individual needs can vary by 20–30% or more, and this table does not cover puppies, kittens, seniors, or pets with medical conditions. It is educational information, not veterinary advice.
