Cat Calorie Calculator: Precise Daily Calorie Needs for Your Feline

Determine your cat's daily calorie requirements with our scientifically-based calculator. Get personalized feeding recommendations based on weight, activity level, age, and specific health conditions to maintain optimal feline nutrition.

How to Use the Cat Calorie Calculator

Follow these simple steps to calculate your cat's precise daily calorie needs:

1. Enter your cat's weight in kilograms (use our converter if you have pounds)
2. Select activity level: Low (indoor/sedentary), Moderate (some play), or High (very active)
3. Choose health conditions: Overweight, underweight, pregnant/nursing, or senior status
4. Get instant results with detailed calculation breakdown

The calculator uses the Resting Energy Requirement (RER) formula: RER = 70 × (weight in kg)^0.75, then applies activity and health multipliers for accuracy.

Cat Calorie Requirements by Weight and Activity

Standard Daily Calorie Needs

• 2kg cat (4.4 lbs): 150-240 calories per day
• 3kg cat (6.6 lbs): 200-320 calories per day
• 4kg cat (8.8 lbs): 240-380 calories per day
• 5kg cat (11 lbs): 280-450 calories per day
• 6kg cat (13.2 lbs): 320-510 calories per day

Activity Level Multipliers

• Low Activity (1.3x): Indoor cats, minimal play
• Moderate Activity (1.5x): Regular play sessions
• High Activity (1.8x): Very active, outdoor access

Special Health Condition Adjustments

Weight Management

• Overweight cats: Reduce calories by 20% (0.8x multiplier)
• Underweight cats: Increase calories by 20% (1.2x multiplier)

Life Stage Considerations

• Senior cats (7+ years): Slightly reduced needs (0.9x multiplier)
• Pregnant/nursing cats: Triple calorie requirements (3.0x multiplier)

Real-World Cat Feeding Examples

Example 1: Indoor Adult Cat

• Weight: 4kg, Low activity, No health issues
• Calculation: 70 × (4)^0.75 × 1.3 = 246 calories/day

Example 2: Senior Overweight Cat

• Weight: 5.5kg, Low activity, Overweight + Senior
• Calculation: 70 × (5.5)^0.75 × 1.3 × 0.8 × 0.9 = 285 calories/day

Example 3: Pregnant Cat

• Weight: 3.5kg, Moderate activity, Pregnant
• Calculation: 70 × (3.5)^0.75 × 1.5 × 3.0 = 900 calories/day

Converting Cat Food to Daily Portions

Once you know your cat's calorie needs:

1. Check food packaging for calories per cup/can
2. Divide daily calories by food calories per serving
3. Split into multiple meals (2-3 feedings recommended)
4. Monitor weight and adjust portions as needed

Frequently Asked Questions About Cat Calories

How many calories should my cat eat per day?

The average adult cat needs 200-300 calories daily, but this varies significantly based on weight, activity level, and health conditions. Use our calculator for precise requirements.

Do indoor cats need fewer calories than outdoor cats?

Yes, indoor cats typically need 20-30% fewer calories due to lower activity levels. Select "Low Activity" in our calculator for indoor cats.

How do I know if my cat is overweight?

A healthy cat should have a visible waist when viewed from above, and you should feel (but not see) their ribs. Overweight cats need reduced calorie intake.

Should senior cats eat fewer calories?

Senior cats (7+ years) often need 10% fewer calories due to decreased metabolism and activity, unless they're underweight or have specific health conditions.

How much should pregnant cats eat?

Pregnant and nursing cats need 2-4 times their normal calorie intake. Our calculator uses a 3x multiplier for safety and optimal kitten development.

Can I use this calculator for kittens?

This calculator is designed for adult cats. Kittens have rapidly changing nutritional needs and should follow veterinarian-specific feeding guidelines.

What if my cat has multiple health conditions?

The calculator applies all selected health condition multipliers. However, consult your veterinarian for cats with complex medical needs.

How accurate is the calorie calculation?

Our calculator uses veterinary-approved formulas (RER method) with standard multipliers. Individual cats may vary by ±10-15% based on metabolism and breed.
