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 weightEstimated 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.
