Ideal weight

Is your cat’s weight about right?

Choose a breed and weight

Pick the breed and current weight to see an estimate.

This is an estimate based on typical weight ranges for the breed.Ideal weight varies widely with frame and age even within a breed, and weight alone is not enough to judge. Body shape is assessed with BCS (Body Condition Score) — whether you can feel the ribs under a thin layer of fat, and whether there is a gentle waist when seen from above. Consult your vet about any weight change that concerns you.

How to read body condition (BCS)

Check by touch and sight alongside the number on the scale.

Underweight Ribs felt immediately; pronounced waist
Ideal Ribs felt under a thin layer of fat; gentle waist
Overweight Ribs hard to feel; little or no waist
