Cat Weight Chart


Your vet's office probably has a cat weight chart pinned up on one of the walls. You can use this chart to determine whether or not your cat is under or overweight.



Two common questions asked by cat owners are "what is a healthy weight for my cat?" and "is there a cat body weight chart I can use?"

We covered healthy cat weight and the need to keep your cat trim. On this page, we'll look at the same type of cat weight chart that your vet would reference to evaluate your kitty (often referred to as a cat body condition chart).

One chart is from the Iams cat food company and the other is from the Purina cat food company. If you're familiar with the claims by cat health experts that dry cat food, along with "free choice" feeding options is largely the cause of obesity in cats, you might note the irony.

While each chart uses a slightly different description for each of the cat body types, they both agree on the basics.
