1. What is the Weight Loss Calorie Calculation?

The weight loss calorie calculation for cats is based on the Resting Energy Requirement (RER) multiplied by 0.8. This provides a safe calorie reduction for gradual weight loss in overweight cats.

2. How Does the Calculator Work?

The calculator uses two formulas:

And then for weight loss:

Where:

• RER — Resting Energy Requirement (kcal/day)
• Weight — Cat's current body weight in kilograms
• 0.8 — Factor for safe weight loss (80% of maintenance)

Explanation: The RER represents the calories needed at rest, and multiplying by 0.8 creates a moderate calorie deficit for gradual weight loss.

3. Importance of Weight Loss Calories

Details: Proper calorie calculation is essential for safe feline weight loss. Too rapid weight loss can cause hepatic lipidosis (fatty liver disease), while insufficient reduction won't achieve weight loss.

4. Using the Calculator

Tips: Enter your cat's current weight in kilograms. For accurate results, weigh your cat regularly and adjust the calorie intake as weight changes.

5. Frequently Asked Questions (FAQ)

Q1: How fast should my cat lose weight?
A: Ideal weight loss is 1-2% of body weight per week. For a 5kg cat, this means 50-100g per week.

Q2: What if my cat isn't losing weight on these calories?
A: Consult your veterinarian before reducing further. Some cats may need adjustment to 70% of RER under veterinary supervision.

Q3: Can I use this for kittens?
A: No, this calculator is for adult cats only. Kittens have different nutritional requirements.

Q4: Should I adjust for activity level?
A: This calculation assumes average activity. Very active cats may need slightly more, but consult your vet before adjusting.

Q5: How often should I recalculate?
A: Recalculate every time your cat loses 10% of body weight, or at least monthly during weight loss.
