Daily Calorie Needs by Cat Age & Weight

Cat Calorie Calculator for Kittens (Under 1 Year)

Kittens require 2-2.5× more calories than adult cats for healthy growth. Use our cat calorie calculator to ensure proper nutrition during this critical development stage. Our cat calorie calculator provides specialized results for kittens.

Adult Cat (1-7 Years)

Adult cats typically need 20-35 calories per pound for weight maintenance. Spayed/neutered cats require about 20% fewer calories to prevent weight gain.

Senior Cat (7+ Years)

Senior cats generally need 15-25 calories per pound due to reduced activity levels. Regular monitoring helps maintain healthy weight in older cats.

RER Formula & Professional Calculation Method

Our cat calculator uses the veterinary-standard RER (Resting Energy Requirement) formula: 70 × (body weight in kg)^0.75. This baseline is then multiplied by activity factors to determine total daily calorie requirements for your cat. The calculator ensures accuracy.

Activity multipliers include: Kittens (2.0-2.5×), Active adults (1.4×), Indoor adults (1.2×), Senior cats (1.1×), and Weight loss (0.8×).

This method is used by veterinary professionals and pet nutrition experts worldwide for accurate calorie calculations.
