Feline Body Condition Score Chart (1 to 9)
The 9-point feline body condition score (BCS) chart: what each score 1 to 9 means by ribs, waist, and fat pad, why 5 is ideal, and muscle condition in senior cats.
Quick answer: The feline body condition score (BCS) is a 9-point scale where 5 out of 9 is ideal. At a 5, the ribs are easily felt under a thin layer of fat, a waist is visible from above, and the abdominal fat pad is minimal. Scores of 6 to 7 indicate overweight, 8 to 9 indicate obese, and 1 to 4 indicate underweight. Each point above 5 equals roughly 10 to 15 percent over ideal body weight.
Feline Body Condition Score Chart (9-Point Scale)
Use touch as well as sight. Feel along the ribs, look down at the waistline from above, and feel the belly for the fat pad just in front of the back legs. The chart below describes what each score feels and looks like.
| Score | Category | What You Feel and See |
|---|---|---|
| 1 | Emaciated | Ribs, spine, and hip bones visible from a distance. No palpable body fat. Severe abdominal tuck and obvious loss of muscle. |
| 2 | Very thin | Ribs easily seen and felt with no fat cover. Spine and hips prominent. Obvious waist and tucked-up belly. |
| 3 | Thin | Ribs easily felt with minimal fat. Spine readily felt. Obvious waist behind the ribs. Minimal belly fat. |
| 4 | Underweight | Ribs felt with little fat cover. Noticeable waist behind the ribs. Slight abdominal tuck. Little to no fat pad. |
| 5 | Ideal | Well-proportioned. Ribs easily felt under a thin layer of fat. Visible waist behind the ribs from above. Minimal abdominal fat pad. |
| 6 | Overweight | Ribs felt under slight excess fat. Waist still present but less distinct. Abdominal fat pad noticeable. |
| 7 | Heavy | Ribs hard to feel under moderate fat. Waist poorly defined. Rounded belly with a moderate fat pad. |
| 8 | Obese | Ribs not felt under heavy fat. No waist. Obvious rounded abdomen with a prominent fat pad and fat over the lower back. |
| 9 | Grossly obese | Ribs not felt under thick fat. Heavy fat over the lower back, face, and limbs. Distended belly with no waist. |
As a rule of thumb, each score above the ideal 5 represents about 10 to 15 percent over ideal body weight. A cat that should weigh 10 pounds at a 5 is roughly 11 to 11.5 pounds at a 6 and 12 to 13 pounds at a 7.
Muscle Condition and Senior Cats (Sarcopenia)
Body condition scoring measures fat, not muscle, so it is paired with a separate muscle condition score. This matters most in older cats. With age, cats commonly lose muscle mass through a process called sarcopenia, and they can do so even while body fat stays the same or increases. A senior cat can therefore read a normal BCS yet feel bony over the spine, shoulder blades, and hips.
Muscle condition is graded as normal or as mild, moderate, or severe muscle loss, assessed by feeling over the skull, shoulder blades, spine, and wings of the hips. Significant muscle loss in a senior cat warrants a veterinary workup, because it can signal kidney disease, hyperthyroidism, or insufficient protein intake. The 9-point body condition scale and muscle condition scoring used here follow the framework promoted by the World Small Animal Veterinary Association (WSAVA) Global Nutrition Committee.
Putting It to Work
Score your cat monthly at home and weigh on a digital scale to catch trends early. If your cat is above or below ideal, your veterinarian can set a target weight and a measured feeding plan. Weight loss in cats must be gradual: rapid loss can trigger hepatic lipidosis, a serious liver condition, so always change a cat's calories under veterinary guidance.

Frequently Asked Questions
What is a healthy body condition score for a cat?
On the 9-point feline body condition score (BCS) scale, an ideal score is 5 out of 9. At a 5, you can feel your cat's ribs easily under a thin layer of fat, see a visible waist behind the ribs when viewed from above, and feel only a small abdominal fat pad. Scores of 6 and 7 mean overweight, 8 and 9 mean obese, and scores of 1 to 4 mean the cat is too thin.
How do I check my cat's body condition score at home?
Use three quick checks. First, run your hands along the ribs: at an ideal weight you feel them easily with a light fat cover, like feeling your knuckles through the back of your hand. Second, look down from above: you should see a slight waist behind the ribs. Third, feel the belly for the abdominal fat pad in front of the back legs. No ribs and no waist suggest overweight, while sharply visible ribs and bones suggest underweight.
What does each point on the cat BCS scale mean in pounds?
On the 9-point scale, each point above the ideal 5 represents roughly 10 to 15 percent over ideal body weight. So a cat that should weigh 10 pounds at a BCS of 5 would be around 11 to 11.5 pounds at a 6, and around 12 to 13 pounds at a 7. The scale is a body-composition tool rather than an exact weight chart, so it is used alongside the scale, not instead of it.
Why can a senior cat be a normal weight but still look thin?
Older cats can lose muscle mass with age, a process called sarcopenia, even while keeping or gaining body fat. The scale may read normal while the cat feels bony over the spine and shoulders and soft elsewhere. This is why vets assess a separate muscle condition score in addition to body condition. A senior cat losing muscle needs a veterinary workup, because it can signal kidney disease, hyperthyroidism, or inadequate protein.
Is a body condition score the same as a muscle condition score?
No. Body condition score estimates how much fat a cat carries, while muscle condition score estimates how much muscle a cat has, graded as normal or mild, moderate, or severe muscle loss. They are assessed separately because a cat can be overweight in fat yet losing muscle at the same time. Muscle is checked by feeling over the skull, shoulder blades, spine, and hips. Both scores together give the truest picture, especially in seniors.
My cat is a 7 out of 9. How much weight should it lose?
A BCS of 7 is roughly 20 to 30 percent above ideal weight, so a cat that should weigh 10 pounds may need to lose about 2 to 3 pounds. Safe feline weight loss is slow, usually no more than about 0.5 to 2 percent of body weight per week, because rapid loss in cats can trigger a dangerous liver condition. Your vet can set a target weight and a calorie plan, often using a measured therapeutic diet.
Does body condition scoring work for long-haired cats?
Yes, but you have to rely more on touch than on looking. A thick coat can hide both ribs and a waistline, so a fluffy cat may look heavier or leaner than it is. Run your hands firmly along the ribs, spine, and belly to feel the actual fat cover rather than judging by appearance. When in doubt, ask your vet to score your cat and show you what an ideal 5 feels like on your specific cat.
