When you know how much your cat weighs compared to their human equivalent, it can be easier to determine if they are overweight or underweight. However, it is important to understand that a number on the scale does not necessarily tell the whole story.

Regardless of their weight, all cats should be in good body condition. This is determined by assessing their body condition score (BCS) on a 9-point scale, which involves looking at and feeling their body, specifically the ribs, hips, waistline and belly. Cats should be in a 3 or 5 BCS, which means they are neither too thin nor too fat.

Is Your Cat a Healthy Weight? Use This Cat Weight Calculator

The best way to get a more accurate idea of how your cat is doing with regard to their weight is by consulting their veterinarian. They will evaluate their breed, age and activity level and help you formulate a plan to keep them at their ideal healthy weight through annual checkups.

You can also use our Cat weight calculator to estimate your pet’s daily caloric needs based on their weight, activity level, body condition score and whether or not they are neutered. The results will show you how many calories per day are needed to maintain their current weight and provide the energy they need for their activities.

We recommend weighing your cat at home once every 2-4 weeks to monitor their weight and make any necessary adjustments to their diet. A gradual increase in food may be needed if their weight starts to creep up, while a sudden decrease could indicate an underlying health condition that requires veterinary attention.
