Easily calculate your cat's BMI with our Cat BMI Calculator. Check if your cat is underweight, normal, overweight, or obese for a healthier life.
Maintaining a healthy weight is essential for your cat’s well-being. Cats, just like humans, can suffer from obesity, which leads to health problems such as diabetes, arthritis, and heart disease. This is why we have developed the Cat BMI Calculator, which helps pet owners determine whether their cat is underweight, normal, overweight, or obese based on their weight and body length.
Understanding your cat’s Body Mass Index (BMI) is a crucial step in ensuring they stay fit and healthy. In this guide, we will explain how to calculate a cat’s BMI, the ideal weight ranges, and how to interpret the results.
The formula for calculating a cat’s BMI is:
BMI = Weight (kg) ÷ (Length (m) × Length (m))
Where:
If your cat’s weight is in pounds (lbs) or length in inches (in), you can convert:
For example, if a cat weighs 4.5 kg and has a length of 0.45 meters, the BMI calculation would be:
BMI = 4.5 ÷ (0.45 × 0.45) = 22.2
This means the cat is slightly overweight based on standard BMI ranges.
| BMI Range | Weight Status |
|---|---|
| Below 15 | Underweight |
| 15 – 18.9 | Normal |
| 19 – 22.9 | Overweight |
| 23 and above | Obese |
A healthy cat BMI falls between 15 and 18.9, meaning the cat is at an ideal weight. If your cat’s BMI is 19 or higher, you should consult a vet for proper weight management.
| Cat Age | Average Weight (kg) | Average Weight (lbs) |
|---|---|---|
| 6 months | 2 - 3 kg | 4.4 - 6.6 lbs |
| 1 year | 3 - 5 kg | 6.6 - 11 lbs |
| 2+ years | 3.5 - 6.5 kg | 7.7 - 14.3 lbs |
A cat weighing 13 lbs (5.9 kg) may be slightly overweight depending on its body structure. A 15 lb (6.8 kg) cat is usually overweight, while a 17 lb (7.7 kg) cat is likely obese unless it is a large breed.
If your cat falls in the overweight or obese category, consult your vet to develop a weight management plan including diet and exercise.
A cat’s BMI is an essential indicator of its health. Keeping your cat at a normal weight helps prevent health issues and ensures a longer, happier life. If your cat is underweight or overweight, take action by adjusting its diet and exercise routine.
Using our Cat BMI Calculator makes it easier for pet owners to track their cat’s weight and ensure a healthy lifestyle. Regular check-ups with a vet, along with proper nutrition and activity, will help your cat stay in the best shape possible.
A normal BMI for a cat ranges from 15 to 18.9.

Yes, a 15 lb (6.8 kg) cat is generally considered overweight unless it is a large breed like a Maine Coon.
