1. What is the Weight Loss Calorie Formula for Cats?

The formula calculates the Maintenance Energy Requirement (MER) for cats needing to lose weight by multiplying the Resting Energy Requirement (RER) by 0.8. This creates a safe calorie deficit for gradual weight loss.

2. How Does the Calculator Work?

The calculator uses the weight loss calorie formula:

Where:

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

Explanation: The formula provides a safe calorie reduction for feline weight loss while maintaining essential nutrient intake.

3. Importance of Proper Calorie Calculation

Details: Accurate calorie calculation is crucial for safe, effective 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: \( RER = 70 \times (body\ weight\ in\ kg)^{0.75} \).

5. Frequently Asked Questions (FAQ)

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

Q2: When should I adjust the calorie intake?
A: Re-evaluate every 2-4 weeks and adjust based on weight loss progress and body condition score.

Q3: What if my cat isn't losing weight on this calculation?
A: Consult your veterinarian. Some cats may need further calorie reduction (to 0.7×RER) under veterinary supervision.

Q4: Can I use this for kittens?
A: No, this formula is for adult cats only. Kittens have different nutritional requirements.

Q5: Should I only rely on calorie restriction for weight loss?
A: Combine with increased activity and environmental enrichment for best results.
