1. What is the Cat Weight Loss Calorie Calculation?

The MER (Maintenance Energy Requirement) calculation for weight loss in cats is a method to determine the appropriate calorie intake to help a cat lose weight safely. It's based on reducing the RER (Resting Energy Requirement) by 20%.

2. How Does the Calculator Work?

The calculator uses the weight loss formula:

Where:

• \( MER \) — Maintenance Energy Requirement for weight loss (kcal/day)
• \( RER \) — Resting Energy Requirement (kcal/day)
• 0.8 — 20% reduction factor for safe weight loss

Explanation: This formula provides a safe calorie reduction to promote gradual weight loss in cats without causing nutritional deficiencies.

3. Importance of Proper Calorie Calculation

Details: Accurate calorie calculation is crucial for safe feline weight loss. Too rapid weight loss can cause hepatic lipidosis, while insufficient reduction won't achieve weight loss goals.

4. Using the Calculator

Tips: Enter the cat's RER in kcal/day. The RER can be calculated using the formula: \( RER = 70 \times (body\ weight\ in\ kg)^{0.75} \). Always consult with a veterinarian before starting a weight loss program.

5. Frequently Asked Questions (FAQ)

Q1: How fast should a cat lose weight?
A: Ideal weight loss is 1-2% of body weight per week. Rapid weight loss can be dangerous for cats.

Q2: Can I use this for all cats?
A: This is a general guideline. Individual needs may vary based on activity level, health status, and other factors.

Q3: What if my cat isn't losing weight?
A: Consult your veterinarian. They may recommend further calorie reduction (up to 0.6 × RER) or investigate other health issues.

Q4: How do I know my cat's RER?
A: RER can be calculated as 70 × (body weight in kg)^0.75 or estimated as 30 × (body weight in kg) + 70 for simplicity.

Q5: Should I adjust the calories as my cat loses weight?
A: Yes, recalculate RER and MER every 2-4 weeks as weight changes to maintain appropriate calorie intake.
