FAQs
How much should I feed my cat to lose weight?
The amount depends on your cat's current weight, target weight, activity level, and chosen weight loss rate. Our calculator provides a personalized calorie target with a safe 20-30% reduction from maintenance calories.
How long will it take for my cat to reach their target weight?
The timeline depends on how much weight needs to be lost and the chosen weight loss rate. A safe rate is 1-2% of body weight per week. Our calculator estimates the timeline based on these factors.
Is it safe to reduce my cat's calories by 30%?
A 30% calorie reduction is the maximum safe deficit and should only be used under veterinary supervision. Most cats do well with a 20-25% reduction. Always consult your veterinarian before starting a weight loss program.
What is hepatic lipidosis and how can I prevent it?
Hepatic lipidosis is a serious liver condition that can occur in cats who lose weight too quickly or stop eating. Gradual weight loss (1-2% per week) and ensuring your cat continues to eat regularly helps prevent this condition.
What if my cat needs to lose more than 20% of their weight?
Weight loss exceeding 20-30% of current body weight should be done under close veterinary supervision. Your veterinarian can help create a safe, monitored weight loss plan and check for underlying health issues.
How often should I feed my cat during weight loss?
Multiple small meals (2-4 times per day) can help manage hunger and maintain energy levels. Our calculator provides a feeding schedule based on your chosen frequency.
