If you're searching for a free BMI calculator for cats, you're in the right place. Our feline BMI tool is vet-approved and helps cat owners calculate ideal weight ranges based on breed, age, and body condition score (BCS).
Veterinary Insight: A 2024 AAFP study found 60% of domestic cats are overweight, with indoor neutered males at highest risk. Proper BMI management can add 2-4 years to your cat's lifespan.
Cats use a 9-point Body Condition Score (BCS) system:
| Breed | Healthy Weight | BCS Target | Special Considerations |
|---|---|---|---|
| Domestic Shorthair | 8-12 lbs | 4.5-5 | Prone to middle-age spread |
| Maine Coon | 12-25 lbs | 5 | Large frame ≠ overweight |
| Siamese | 6-12 lbs | 4 | Naturally lean build |
| Persian | 7-14 lbs | 4.5 | Fluffy coat hides weight |
Ragdolls and Norwegian Forest Cats naturally carry more weight due to dense bones and muscle mass. Focus on BCS rather than scale numbers for these breeds.
Feed 20-30 calories per pound of ideal weight. Example: 10lb cat needs 200-300 calories/day.
Adult cats do best with 3-4 small meals rather than free-feeding to mimic natural hunting patterns.
10 minutes of active play twice daily can burn up to 20% of daily calories. Try feather wands or laser pointers.
| Life Stage | BCS Target | Special Notes |
|---|---|---|
| Kitten (0-1yr) | BCS 5-6 | Extra calories for growth |
| Adult (1-7yrs) | BCS 4-5 | Monitor indoor cats closely |
| Senior (7+yrs) | BCS 4 | Muscle loss common |
Warning: Sudden weight loss in cats can indicate hyperthyroidism or diabetes. Consult your vet if your cat loses >10% body weight unexpectedly.
