Purina Body Condition Tool for Checking Your Cat's Ideal Weight

Keeping your cat at a healthy weight is important for their wellbeing. But sometimes it is difficult to tell what that ideal weight should be. Discover an easy, step-by-step tool to check your cat's current and ideal size.

Cats come in all shapes and sizes, so it’s sometimes tricky to determine whether yours is the right weight or not – after all, you love them regardless of any extra pounds! But size does matter when it comes to health, and excess weight on your cat can cause problems. So, what is a healthy cat weight?

What is the average cat weight?

The ideal cat weight varies from breed to breed. According to WebMD, the average cat weight is about 10 pounds, but while smaller breeds can be happy and healthy while weighing as little as 5 pounds, larger breeds such as the Maine Coon can be 20 pounds and happy.

This is where cat weight charts and body condition tools come in handy for checking the healthy cat weight for your pet.

Why is keeping a healthy weight for a cat important?

A healthy cat is a happy cat, and one much less prone to illness and health problems. If your cat is overweight, they may not live as long as their healthy counterparts, and they’ll be less able to enjoy themselves when they’re exercising and playing because of potential joint problems. Some specific concerns that can develop from excess weight include:

  • Arthritis, joint damage, and joint pain
  • Type 2 diabetes
  • Heart disease
  • Reduced exercise endurance and stamina
  • Increased anesthetic and surgical risks
  • Reduced liver function due to a fatty liver

What is a cat body condition tool?

We try to avoid putting the emphasis on weight because there’s more to having a healthy cat than weight alone.

Created by pet care experts, our Body Condition Tool is designed to help you determine if your cat is a healthy size overall and encourages you to get hands-on with your cat, to get to know their actual size underneath all that fur!

How to use our body condition tool for checking the ideal cat weight?

You should look at your cat from every angle to get an all-round view – this is important in finding a healthy weight for a cat. Take your time and be gentle – your cat might not be used to being handled like this, but they’ll soon get used to it.

Use the slider below to select the image that most closely matches your cat, and we’ll be able to tell you if they may be underweight, overweight, or just right.

Example of body condition scoring for healthy cat weight

Remember, weight alone won’t tell you if your pet is the right size. To find out your cat’s body condition score, you’ll need to get hands-on!

Not sure if you’re judging it properly? The ideal healthy cat weight is leaner than you might think, mainly because pet owners tend to underestimate the weight of their cats. Each individual cat will require different food, a different meal size, and varying levels of cat exercise. Depending on their body shape, size, and breed, it’s quite possible that two cats could weigh exactly the same, but one would be overweight and the other would be underweight!

Take a look at these examples of cats that have scored against the Body Condition Tool. There's a lot of variety here - it's not just about weight, but about the size and shape, too.
