1. What is the Ohio State Cat Weight Loss Formula?

The Ohio State Cat Weight Loss Formula calculates the appropriate caloric intake for feline weight loss by taking 80% of the Resting Energy Requirement (RER). This safe, gradual approach helps cats lose weight without risking hepatic lipidosis.

2. How Does the Calculator Work?

The calculator uses the following equations:

Where:

• RER — Resting Energy Requirement (kcal/day)
• Weight — Current body weight in kilograms
• 0.8 — 80% of RER for safe weight loss

Explanation: The formula first calculates the cat's basic energy needs at rest, then reduces it by 20% to create a safe calorie deficit for gradual weight loss.

3. Importance of Controlled Weight Loss in Cats

Details: Rapid weight loss in cats can cause serious health issues like hepatic lipidosis. A controlled reduction of 1-2% body weight per week is recommended.

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: Aim for 1-2% of body weight per week. For a 5kg cat, this would be 50-100g per week.

Q2: What if my cat isn't losing weight?
A: Consult your vet. You may need to reduce calories further (but not below 60% RER) or rule out medical issues.

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 is a starting point. Active cats may need slightly more, sedentary cats slightly less.

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