How the Cat Food Calculator Works
A cat’s daily calories come from its resting energy requirement — 70 times its weight in kilograms to the power 0.75 — times a factor for its life stage. A typical 10-lb indoor, neutered cat needs about 260 calories a day. Kittens need far more to grow, while cats on a diet need less.
Match the total to the calories listed on your cat’s food (canned and dry differ a lot), and weigh portions rather than free-feeding to prevent obesity, which is very common in cats.
daily calories = 70 × (kg)^0.75 × life-stage factor
Frequently Asked Questions
How many calories does my cat need?
About 70 × (weight in kg)^0.75 × a life-stage factor. A 10-lb indoor cat needs roughly 260 calories a day.
How much should I feed a kitten?
Kittens need far more — often two to two-and-a-half times the resting requirement — to support growth.
Wet or dry food portions?
Both work; just match the total daily calories, since canned food is much less calorie-dense per gram than kibble.
