Ideal BMI for Cats – Healthy Weight Guide
Cats may seem sleek and agile, but maintaining a healthy weight is as important for them as it is for humans. Understanding your cat's ideal Body Mass Index (BMI) helps prevent long-term health risks like diabetes, arthritis, and even heart disease.
Did you know? Over 60% of domestic cats in the U.S. are either overweight or obese.
What is the Ideal BMI for Cats?
While traditional BMI calculations aren’t used for cats the way they are for humans, veterinarians assess feline BMI through a body condition score (BCS). On a scale of 1 to 9, a healthy cat should ideally fall between 4 to 5.
This score reflects the visible waist, abdominal tuck, and the ease with which ribs can be felt (but not seen). It's a visual and physical assessment used to estimate your cat’s fat-to-muscle ratio.
How to Know if Your Cat is Overweight or Underweight?
- Underweight (BCS 1–3): Ribs, spine, and pelvis visible. Little to no fat. Loss of muscle mass.
- Ideal (BCS 4–5): Ribs easily felt but not visible. Visible waist behind the ribs when viewed from above.
- Overweight/Obese (BCS 6–9): Ribs not easily felt. No waist. Sagging abdomen or fat deposits.
Tips to Maintain a Healthy Weight for Cats
- Feed a vet-approved portion of high-protein, low-carb cat food.
- Limit treats to no more than 10% of daily calories.
- Encourage activity with toys, climbing posts, and regular playtime.
- Weigh your cat monthly to track changes.
- Use a Pet BMI Calculator to assess progress.
Why Cat Obesity Should Not Be Ignored
Extra weight can silently increase your cat’s risk of diseases, reduce mobility, and shorten their life expectancy. Catching the weight gain early helps avoid costly vet bills and painful health issues later.
A healthy cat is a happy cat — and a longer-living one. Always consult your vet before making diet or lifestyle changes.
