1. What is the Maintenance Energy Requirement?

The Maintenance Energy Requirement (MER) estimates the daily calorie needs for an average adult cat to maintain its current weight. It accounts for the cat's metabolic rate and typical activity level.

2. How Does the Calculator Work?

The calculator uses the MER equation:

Where:

• \( weight_{kg} \) — Cat's weight in kilograms
• 0.75 — Metabolic scaling exponent
• 1.2 — Activity factor for average pet cats

Explanation: The equation accounts for the non-linear relationship between body weight and metabolic rate in cats.

3. Importance of MER Calculation

Details: Accurate MER estimation is crucial for maintaining healthy weight in cats, preventing obesity or undernourishment, and designing appropriate feeding plans.

4. Using the Calculator

Tips: Enter your cat's weight in kilograms. For best results, weigh your cat regularly as small changes can significantly affect calorie needs.

5. Frequently Asked Questions (FAQ)

Q1: Is this calculator suitable for all cats?
A: This provides a general estimate for healthy adult cats. Kittens, seniors, or cats with health conditions may have different requirements.

Q2: How often should I recalculate my cat's MER?
A: Recalculate whenever your cat's weight changes by more than 10% or every 3-6 months for stable-weight cats.

Q3: What if my cat is very active or sedentary?
A: Adjust the activity factor (1.2) - use 1.0 for inactive cats, 1.4 for very active cats, or consult your vet.

Q4: My cat needs to gain/lose weight - how to adjust?
A: For weight loss, feed 80% of MER. For weight gain, feed up to 120% of MER. Always consult your vet first.

Q5: What about pregnant or nursing cats?
A: Pregnant/nursing cats have much higher energy needs (up to 2-4x MER) - consult your vet for specific recommendations.
