Average Cat Weight: Healthy Weight Ranges for 25+ Breeds
How much should your cat weigh? The answer depends heavily on breed, age, sex, and body frame. A healthy Maine Coon male can weigh 18-22 lbs without being overweight, while a Siamese at the same weight would be severely obese.
This guide provides weight ranges for 25+ popular breeds, teaches you how to assess your cat’s body condition, and offers safe weight management advice. For a quick check, try our interactive Cat Weight Chart.
Average Cat Weight: The Quick Numbers
For the most common cat type — the Domestic Shorthair (mixed breed) — the average healthy weight ranges are:

How to Tell If Your Cat Is Overweight
Numbers on a scale are only part of the picture. The Body Condition Score (BCS) system, used by veterinarians worldwide, is the most reliable way to assess whether your cat is at a healthy weight. The WSAVA-endorsed 9-point scale works like this:
BCS 1-3: Underweight
- Ribs, spine, and hip bones easily visible
- Obvious waist and abdominal tuck
- Very little or no fat cover
- Muscle wasting may be present
Action: See your vet. Unintentional weight loss can indicate thyroid disease, diabetes, kidney disease, dental pain, cancer, or parasites.
BCS 4-5: Ideal Weight
- Ribs easily felt with gentle pressure but not prominently visible
- Clear waist when viewed from above (an “hourglass” shape)
- Slight abdominal tuck when viewed from the side
- Thin layer of fat over ribs
This is the target. A BCS 5 cat has good muscle mass, a defined waist, and ribs you can feel but not see.
BCS 6-7: Overweight
- Ribs hard to feel under a noticeable fat layer
- Waist barely visible or absent
- Rounded belly when viewed from the side
- Fat deposits beginning on legs and face
Action: Reduce portions by 10-15% and increase play activity. Recheck in 4-6 weeks.
BCS 8-9: Obese
- Ribs not palpable under thick fat deposits
- No visible waist — barrel-shaped body
- Pronounced pendulous belly
- Fat deposits on limbs, face, and over tail base
Action: Veterinary consultation is strongly recommended. A supervised weight loss plan with regular monitoring is safer than DIY dieting, which can cause hepatic lipidosis (fatty liver disease) if too aggressive.
Weight Management: How to Help Your Cat Lose Weight Safely
Cat weight loss must be gradual — no more than 1-2% of body weight per week. Rapid weight loss in cats can cause hepatic lipidosis, a potentially fatal liver condition. Always work with your vet.
Safe Weight Loss Plan:
- Get a vet assessment — rule out medical causes of weight gain (hypothyroidism, Cushing’s) and set a target weight
- Calculate calorie needs — your vet will set a daily calorie target (typically 80% of calories needed for the target weight, not current weight)
- Measure all food — use a kitchen scale or measuring cup for every meal
- Eliminate or dramatically reduce treats — or switch to low-calorie treats
- Increase activity — 15-20 minutes of active play per day (wand toys, laser pointer, crinkle balls)
- Weigh monthly — track progress and adjust as needed
- Be patient — healthy weight loss for a cat is 0.5-1 lb per month
Use our Cat Calorie Calculator to find a starting calorie target based on your cat’s current weight and goal.
The Health Risks of Cat Obesity
Overweight cats face significantly higher risks of:
- Diabetes mellitus — obese cats are 4x more likely to develop diabetes (per a study in the Journal of Veterinary Internal Medicine)
- Urinary tract disease
- Osteoarthritis — excess weight stresses joints
- Hepatic lipidosis (fatty liver) — paradoxically, both obesity and rapid weight loss increase risk
- Reduced lifespan — overweight cats live an average of 2-3 years less than healthy-weight cats
When a Cat Is Too Thin
Underweight cats (BCS 1-3) also need attention. Common causes include:
- Hyperthyroidism — very common in cats over 10, causes weight loss despite increased appetite
- Chronic kidney disease — gradual weight loss with increased thirst
- Dental disease — pain while eating leads to decreased food intake
- Cancer — unexplained weight loss is a warning sign
- Intestinal parasites — especially in outdoor cats or kittens
- Diabetes — weight loss with increased thirst and urination
If your cat is losing weight without an intentional diet change, see your vet promptly.
