The largest domestic cat breed weighs almost four times the smallest. They are the same species — just selectively bred for opposite goals.

Top 10 Heaviest Cat Breeds
Domestic cat breeds vary far less than dog breeds — about 4x weight ratio versus 50x for dogs. But the breeds at the extremes are immediately recognizable.
| # | Name | Average Adult Weight (kg) | Unit |
|---|---|---|---|
| 1 | Savannah | 9 | kg |
| 2 | Chausie | 9 | kg |
| 3 | Maine Coon | 8 | kg |
| 4 | Ragdoll | 7.50 | kg |
| 5 | Norwegian Forest Cat | 7 | kg |
| 6 | Siberian | 7 | kg |
| 7 | Turkish Van | 6.50 | kg |
| 8 | British Shorthair | 6 | kg |
| 9 | Persian | 5.50 | kg |

Cat Breeds vs Dog Breeds
Cat breeding has produced far less size variation than dog breeding. Maine Coons and Savannahs at ~8-9 kg are the largest mainstream breeds. Singapuras at 3 kg are the smallest. The ratio is ~3x; for dogs (Mastiff vs Chihuahua), it is 50x.
Maine Coon is one of the few naturally large breeds — it evolved its size in the harsh winters of New England, not through deliberate breeding. Savannah cats are hybrids of domestic cats with wild African servals; some early generations approach 11-13 kg.
Most cat breed weights here are average adult males. Females typically weigh 15-25% less. Indoor cats often exceed breed standards due to overfeeding.
Frequently Asked Questions
Which is the largest cat breed?
Maine Coon among standard breeds (~8 kg). Savannah hybrids can reach 9-13 kg.
Which is the smallest?
Singapura averages 3 kg — about half the size of a typical domestic shorthair.
Why don't cat breeds vary as much as dogs?
Cats were domesticated more recently (~10,000 years vs 30,000+ for dogs) and selectively bred for fewer working tasks. Less time, less selection pressure, less variation.
Are these AKC-equivalent figures?
Cats are tracked by CFA (Cat Fanciers’ Association) and TICA. Standards similar in spirit to AKC but with smaller size ranges.
Note: Average adult-male weights in kg per CFA/TICA breed standards.
