Estimated daily calories
— kcal/day
Typical range: — kcal/day Treats ≤10%: up to — kcal/day

This estimate helps identify a starting daily calorie target from meals. Treats are not included in the meal number. If your cat needs to lose weight, the target may need to be adjusted downward under veterinary guidance.

Senior note: Some cats over about 12 years may have increased energy and protein needs to maintain a healthy body condition.
Safety note: Avoid rapid or severe calorie restriction in cats. Sudden food reduction or inappetence can increase the risk of a life-threatening liver condition known as hepatic lipidosis. Work closely with your veterinarian to set safe calorie and feeding goals.
Important: This tool is provided by the World Pet Obesity Association for educational purposes only and should not be used as a substitute for veterinary care. Energy needs vary depending on your pet’s health status, body condition, age, and activity level. Always review any diet or weight plan with your veterinary team, and do not begin a weight-loss program, restrict calories, or start an exercise routine without your veterinarian’s guidance.

About the cat feeding calculator

The Cat Daily Feeding Calculator helps veterinary teams and pet owners estimate daily calorie needs and feeding portions for adult cats based on body weight, body condition, activity level, reproductive status, and weight-management goals. WPOA’s tool supports practical nutrition conversations by translating daily energy estimates into meal planning guidance while accounting for treats, toppers, and other added calories. It is designed to help support obesity prevention, monitored weight management, and clearer feeding recommendations for cats under veterinary guidance.
