Understanding your cat's ideal weight and body condition is essential. Knowing what an ideal cat body condition score looks like will make it easier to spot any irregularities in their weight. This can help you discuss the next steps with your veterinarian to get them back to a healthy weight. 

If your cat is at a healthy weight they will be less likely to have weight-related health issues in the future.

You may not have previously thought about assessing your cat's body condition and weight at home, however, maintaining an ideal weight may help increase their lifespan.

If you regularly monitor your cat's body condition and weight it will be easier to identify when you should seek advice from a veterinarian if there is a noticeable change.

Alongside weighing your cat, using a body condition score is one of the easiest methods to understand whether or not they are at a healthy weight. Normally used by veterinarians, it is a technique that can also be easily used by pet owners at home. Remember, it's important to discuss your cat's body condition with your veterinarian.

How to use a body condition score

A cat body condition score involves looking at their body from above and the side to assess whether they are an ideal weight. As you need to feel their body and look at their shape, you will be able to assess whether they are at a healthy weight more accurately than when only looking at the number on the scale. 

Cat body condition scores use a 9-point system to assess weight. The score starts at 1, indicating your cat is severely underweight and goes up to a 9 at the other end of the scale, which points to severe obesity. 

An ideal body weight according to the score is marked as a 4 or 5. This means you can easily feel their ribs, identify a visible waist from above and can see their abdomen tuck up behind their rib cage when looking at your cat from the side. 

Measuring your cat's body condition score

Follow our easy-to-use cat body condition score below to understand whether your cat is underweight, overweight or at an ideal weight.

Step 1 - Look

Using our body condition score below, check which body shape best matches your cat. When assessing a body condition score, look at your cat from above and from the side. Compare their body shape against those highlighted under each score, from 1 to 9, to see which best matches your cat's physical appearance.

Step 2 - Feel

Using your fingers, gently apply small amounts of pressure around your cat's ribs. If you can clearly feel their ribs without pressure this could indicate they are underweight. However, if you are struggling to feel their ribs without applying a significant amount of pressure this could be a sign of excess weight gain.

Step 3 - Weigh

Check your cat's weight on an appropriate scale. Once you have assessed their body shape and body condition score, knowing their weight will provide a well-rounded view of your cat's body condition. Your veterinarian will be able to address your cat's nutritional needs based on their current and ideal body condition.

 

Cat body condition score 1 - 9

A cat body condition scale ranges from 1 to 9, with 1 indicating a cat is severely underweight, to 9 meaning severely obese. A cat is considered to have an ideal body condition if they score between 4 and 5. Assessing your cat's body condition score is easy to do and can be done while petting your cat.
