How to assess your cat's BCS in 2 minutes

The WSAVA “look-feel-look” protocol, adapted for home use. You don't need equipment — just your hands and good lighting.

Step 1

Feel the ribs

Place both hands lightly on either side of your cat's chest. Ribs should feel like the back of your hand — palpable through a thin layer of fat but not sharp. If ribs feel like your knuckles (bony) your cat is likely underweight; if they feel like your palm (hard to find) your cat is overweight.

Step 2

Look from the side

View your cat standing in profile. There should be a slight upward abdominal tuck behind the rib cage. If the belly sags below the line of the legs and swings when walking, your cat is obese; if the tuck is extreme and spine is visible, your cat is underweight.

Step 3

Look from above

Stand over your cat and look straight down. You should see a visible waist — a slight indentation behind the ribs before the hips. If the outline is oval from head to tail with no waist, your cat is overweight.

Frequently asked questions

How do I use a body condition score for a cat?

Walk through three checks: (1) Feel the ribs — they should feel like the back of your hand under a thin fat layer. (2) Look from above for a waist behind the ribs. (3) Look from the side for a slight abdominal tuck. Match what you see and feel to the 9-point WSAVA chart with the slider on this page. Score 4–5 is ideal for most adult cats.

What is a cat body condition score chart?

A cat body condition score chart maps scores 1–9 to visual and palpation landmarks (ribs, waist, abdominal tuck) and estimated body-fat ranges. WSAVA and Purina publish reference charts; this page adds an interactive slider so you can match what you see and feel to a score at home.

Where can I find a cat BCS chart PDF?

WSAVA publishes printable feline Body Condition Score charts in its Global Nutrition Toolkit (see Sources below). Use the interactive assessor above for a home score, then compare against the official WSAVA PDF if you want a printable reference for your vet visit.

What is a Body Condition Score (BCS) for cats?

BCS is a 1–9 visual and hands-on scale that estimates how much body fat a cat carries. Score 1 is emaciated, 5 is ideal, and 9 is grossly obese. Veterinary bodies (WSAVA, AAFP, Purina Institute) use this 9-point scale because it captures differences that weight alone misses — a 12-lb Maine Coon can be lean while a 12-lb Siamese is obese.

WSAVA cat body condition score: what do “ribs, waist, abdominal tuck” mean?

These are the three key landmarks in the WSAVA look-feel-look check. Ribs should be easily felt under a thin fat layer (not sharp like knuckles, not hidden like a padded palm). From above you should see a waist indentation behind the ribs. From the side you should see a slight upward abdominal tuck behind the rib cage. If ribs are hard to find, waist is lost, and the belly line sags, your cat is likely BCS 6+.

Is there a WSAVA cat BCS 9-point chart PDF?

Yes — WSAVA publishes Body Condition Score charts as part of its Global Nutrition Toolkit. We reference the WSAVA resources in the Sources section below. This page is an interactive version that helps you map what you see and feel (ribs/waist/tuck) to a 1–9 score at home.

What BCS should my cat be?

Most adult cats should sit at BCS 4 or 5 — ribs easily felt with a thin layer of fat, a visible waist when viewed from above, and a slight tuck behind the rib cage from the side. BCS 5 corresponds to roughly 20–24% body fat per the Purina Institute feline chart.

How do I check my cat's BCS at home?

Use the WSAVA look-feel-look protocol: (1) Feel the ribs — they should feel like the back of your hand, not your knuckles and not your palm. (2) Look from the side — there should be a slight upward tuck behind the rib cage. (3) Look from above — you should see a waist indentation behind the ribs. The slider above lets you match your observations to a score.

My cat is BCS 6 — is that an emergency?

No, BCS 6 is not an emergency, but it is the point where proactive action pays off. A cat at 6 carries 25–29% body fat. Reducing daily calories by roughly 10% and re-weighing in 4 weeks is usually enough to trend back to 5. If weight keeps climbing or your cat is already 8–9, see your vet to rule out endocrine disease before starting a diet.

Is BCS the same as weight?

No. Weight is an absolute number; BCS is a proportional estimate of fat cover relative to your cat's frame. Two cats at the same weight can score differently — BCS normalizes for breed and bone structure. Track both: weight weekly, BCS every 2–4 weeks.

How often should I reassess BCS?

For healthy adult cats, reassess every 2–4 weeks. During active weight loss or gain plans, reassess every 2 weeks. Kittens and senior cats (11+) benefit from monthly checks because their body composition shifts faster.

How does cat BCS differ from dog BCS?

The scale is the same (1–9) and the principles are similar, but anatomical landmarks differ. In cats, the abdominal fat pad (primordial pouch vs pathological fat) and waist visible from above are the primary signals. Dogs carry fat differently across breeds — a Greyhound at BCS 5 looks very different from a Labrador at BCS 5.
