Summary
What the Numbers Mean
For a 4 kg neutered adult, RER = 70 × 4^0.75 ≈ 198 kcal and MER = 198 × 1.2 ≈ 238 kcal/day. About 21 kcal can go to treats; the rest — roughly 214 kcal — should come from meals, split across the day.
The Formulas
Veterinary nutritionists use RER = 70 × (weight in kg)^0.75, then scale by life stage: kittens 2.5×, intact adults 1.4×, neutered adults 1.2×, seniors 1.1×, obesity-prone 1.0×, lactating queens 2.0×. Indoor cats typically need about 10% less than outdoor cats.
