Formula
Dogs: RER = 70 x (weight_kg)^0.75, Daily Calories = RER x activity factor (1.2 low, 1.6 moderate, 2.0 active). Cats: ~20 cal/lb x activity factor (0.8 low, 1.0 moderate, 1.2 active). Cups = calories / 375.

How many calories does a cat need per day?
An average indoor cat needs about 20 calories per pound of body weight per day. A 10-lb cat needs approximately 200 calories daily, adjusted for activity level.
