1. What is the MER Equation?

The Maintenance Energy Requirement (MER) equation estimates the daily calorie needs for cats based on their weight and life stage/activity level. It helps ensure proper nutrition without overfeeding or underfeeding.

2. How Does the Calculator Work?

The calculator uses the MER equation:

Where:

• \( weight_{kg} \) — Cat's weight in kilograms
• \( factor \) — Adjustment for life stage and activity level

Explanation: The equation accounts for the non-linear relationship between body weight and metabolic rate, with different factors for different life stages and activity levels.

3. Importance of Calorie Calculation

Details: Accurate calorie estimation is crucial for maintaining healthy weight, preventing obesity, and ensuring proper nutrition during growth, pregnancy, or weight loss programs.

4. Using the Calculator

Tips: Enter your cat's weight in kilograms and select the appropriate life stage/activity factor. For precise measurements, weigh your cat regularly and adjust portions as needed.

5. Frequently Asked Questions (FAQ)

Q1: How often should I recalculate my cat's calorie needs?
A: Recalculate whenever your cat's weight changes by more than 10% or their life stage/activity level changes significantly.

Q2: What if my cat needs to gain or lose weight?
A: For weight loss, reduce calories by 10-20% of MER. For weight gain, increase by 10-20%. Consult your vet for specific recommendations.

Q3: How do I convert my cat's weight from pounds to kilograms?
A: Divide pounds by 2.205 to get kilograms (e.g., 10 lbs ÷ 2.205 = 4.54 kg).

Q4: Are there limitations to this equation?
A: Less accurate for very young kittens, extremely obese cats, or cats with metabolic disorders. Individual needs may vary.

Q5: Should this be the only factor in determining my cat's diet?
A: No, consider also your cat's body condition, health status, and veterinarian's recommendations. MER is just a starting point.
