Most adult cats need around 180–300 calories per day, but calorie requirements vary based on weight, age, activity level, and health condition. A common calculation starts with your cat’s resting energy requirement (RER) and adjusts calories based on lifestyle and weight goals.

How Many Calories Does a Cat Need Per Day? Cat Calorie Guide

Understanding your cat’s daily calorie needs is important for maintaining a healthy weight.

Feeding too many calories can lead to:

• Weight gain

🐱 Average Calories Cats Need Per Day

General guidelines:

These are general estimates.

A 5 kg indoor cat and a 5 kg active outdoor cat may require different calories.

⚖️ How to Calculate Cat Calories

Veterinarians often use energy requirement formulas.

Step 1: Calculate Resting Energy Requirement (RER)

Formula:

RER = 70 × (body weight in kg)⁰·⁷⁵

Example:

A 5 kg cat:

70 × (5⁰·⁷⁵)

≈ 235 calories/day

This is the basic energy requirement.

Step 2: Adjust Based on Lifestyle

Different cats need different calorie levels.

🐱 Adult Indoor Cat

Usually:

1.2 × RER

Example:

5 kg cat:

235 × 1.2

≈ 280 kcal/day

🐈 Weight Loss Cat

Usually:

Around 0.8 × ideal weight RER

Weight loss plans should be gradual.

🐾 Active Cat

May need:

1.4–2 × RER

Outdoor cats or highly active cats burn more energy.

🍼 Kitten Calories

Growing kittens need more calories because they are developing.

They require:

• More protein

• More energy

• More frequent meals
