1. What is the Feline Weight Loss Calculation?

The feline weight loss calculation determines the appropriate caloric intake for cats to safely lose weight. It's based on the Resting Energy Requirement (RER) multiplied by a factor of 0.8 to create a caloric deficit while maintaining health.

2. How Does the Calculator Work?

The calculator uses these formulas:

Where:

• \( RER \) — Resting Energy Requirement (kcal/day)
• \( MER \) — Maintenance Energy Requirement for weight loss (kcal/day)
• \( weight \) — Current body weight in kilograms

Explanation: The calculation first determines the cat's baseline energy needs (RER) then reduces it by 20% to create a safe weight loss plan.

3. Importance of Proper Weight Loss in Cats

Details: Gradual weight loss is crucial for cats to avoid hepatic lipidosis (fatty liver disease). A 1-2% body weight loss per week is generally safe.

4. Using the Calculator

Tips: Enter the cat's current weight in kilograms. The calculator will provide both the RER and the recommended caloric intake for weight loss.

5. Frequently Asked Questions (FAQ)

Q1: Why multiply RER by 0.8 for weight loss?
A: This creates a modest 20% caloric deficit that promotes gradual, safe weight loss while maintaining muscle mass.

Q2: How fast should cats lose weight?
A: Ideal rate is 0.5-2% of body weight per week. Rapid weight loss can be dangerous for cats.

Q3: Should I adjust food amounts over time?
A: Yes, recalculate as the cat loses weight. Every 10% weight loss should prompt a recalculation.

Q4: What if my cat isn't losing weight on this plan?
A: Consult your veterinarian before further reducing calories. Some cats may need more exercise or different food.

Q5: Can I use this for obese cats?
A: Yes, but very obese cats may need veterinary supervision for their weight loss program.
