1. What is the MER Equation?

The MER (Maintenance Energy Requirement) equation estimates a pet's daily calorie needs based on weight and activity/physiological factors. It provides a baseline for determining appropriate food portions.

2. How Does the Calculator Work?

The calculator uses the MER equation:

Where:

• \( W \) — Weight in kilograms (kg)
• \( F \) — Factor based on pet's status

Explanation: The equation accounts for metabolic scaling with body weight (using the 0.75 power) and adjusts for different physiological states with the factor.

3. Importance of MER Calculation

Details: Accurate MER estimation is crucial for maintaining healthy weight, preventing obesity, and ensuring proper nutrition for pets.

4. Using the Calculator

Tips: Enter weight in kg, select appropriate factor based on pet's status. All values must be valid (weight > 0).

5. Frequently Asked Questions (FAQ)

Q1: What are the typical factor values?
A: Factors range from 1.0 (neutered adult) to 2.0 (growing puppy/kitten), with variations for weight management.

Q2: How often should I recalculate MER?
A: Recalculate whenever your pet's weight changes by more than 10% or their physiological status changes.

Q3: Is this suitable for all pets?
A: This is a general guideline. Individual needs may vary based on breed, health status, and activity level.

Q4: What if my pet is overweight?
A: Use the weight loss factor but consult a veterinarian for a tailored weight management plan.

Q5: Can I use this for exotic pets?
A: This equation is primarily for dogs and cats. Other species may require different calculations.
