Frequently Asked Questions
Why do cat calorie calculators give different results?
Calculators can vary by up to 50% because they use different RER formulas, multipliers and activity level assumptions. Our calculator uses veterinary standard formulas: RER = 70 × (weight in kg)^0.75 for extreme cases, or RER = (30 × weight in kg) + 70 for typical cats, with evidence-based multipliers.
How fast can my cat safely lose weight?
Cats should never lose more than 1-2% of their body weight per week. For a 5kg cat, this means a maximum of 50-100g per week. Faster weight loss can cause hepatic lipidosis (fatty liver), a potentially fatal condition. Always consult your veterinarian before starting a weight loss program.
How can I determine my cat's body condition score?
Body condition score is assessed through visual inspection and palpation. An ideal cat (score 4-5) has ribs palpable with slight pressure, waist visible from above, and minimal fat layer. Overweight cats (6-9) have ribs difficult to palpate, no visible waist, and obvious abdominal fat.
How many calories does a growing kitten need?
Kittens have very high caloric needs: kittens 0-4 months need 2.5 times their RER, while kittens 4-12 months need 2.0 times their RER. This can mean 200-400+ calories per day for a small kitten. Kittens should eat every 3-4 hours and have constant access to high-quality food.
How often should I adjust my cat's calories?
Monitor weight weekly and adjust calories as needed. If your cat is losing or gaining weight faster than planned, adjust calories in 10% increments. For senior cats or those with medical conditions, consult your veterinarian every 3-6 months for nutritional assessment.
