1. What is the RER Formula?

The RER (Resting Energy Requirement) formula estimates the daily caloric needs for kittens during growth. It is calculated based on body weight and includes a growth factor multiplier.

2. How Does the Calculator Work?

The calculator uses the RER formula:

Where:

• \( BW \) — Body weight in kilograms (kg)
• 1.2 — Growth factor multiplier for kittens

Explanation: The equation calculates the base energy requirement at rest, adjusted for the additional energy needs during growth in kittens.

3. Importance of RER Calculation

Details: Accurate RER estimation is crucial for determining appropriate feeding amounts to support healthy growth and development in kittens.

4. Using the Calculator

Tips: Enter the kitten's body weight in kilograms. The value must be valid (weight > 0).

5. Frequently Asked Questions (FAQ)

Q1: What does RER stand for?
A: RER stands for Resting Energy Requirement, which is the amount of energy (calories) needed at rest.

Q2: Why is there a growth factor of 1.2?
A: The 1.2 multiplier accounts for the additional energy requirements during the growth phase in kittens.

Q3: How often should I recalculate my kitten's RER?
A: It's recommended to recalculate every 2-4 weeks as kittens grow rapidly, or whenever there's a significant change in weight.

Q4: Is this formula suitable for all kitten breeds?
A: While the formula provides a general estimate, some breeds may have different metabolic rates. Consult your veterinarian for breed-specific advice.

Q5: Can I use this calculator for adult cats?
A: No, this specific formula includes a growth factor. Adult cats have different energy requirements and would use a different multiplier.
