Maine Coon Weight Chart. Healthy Ranges
Weight should always reflect health, not extremes.
Approximate healthy ranges:
3 months. 3 to 5 pounds (1.4 to 2.3 kg) 6 months. 6 to 9 pounds (2.7 to 4.1 kg) 12 months. 9 to 14 pounds (4.1 to 6.3 kg) 24 months. 12 to 18 pounds (5.4 to 8.1 kg) Adult. Genetics determine final range
If weight increases without muscle tone, adjust feeding and activity.
Do Male Maine Coons Get Bigger Than Females
Yes. Male Maine Coons usually grow larger. They develop broader chests and heavier bone structure.
Females remain large but more streamlined. Temperament differences remain minimal.
Does Neutering Affect Maine Coon Size
Neutering timing influences growth pattern.
Early neutering may allow longer bone growth, resulting in taller cats. Proper nutrition matters more than timing alone.
Common Maine Coon Size Myths
