What Is the Average Weight of a Maine Coon?

The Maine coon cat is native to North America and was originally recognized as its own breed in Maine. It is larger and heavier than most cats. Adult Maine coons should weigh between 9 and 18 pounds.
  1. Gender

    • Like most species, a Maine coon's size differs depending on the gender of the animal. Adult male Maine coons typically weigh 13 to 18 pounds, while adult females weigh about 9 to 12 pounds.

    Size vs. Weight

    • Cat Fanciers' website states that Maine coon cats weighing 30 pounds or more are a "Yankee myth." However, as a long-haired breed, Maine coons tend to look bigger than they actually are. They also develop a winter coat that makes them look larger.

    Weight Problems

    • Maine coon cats may gain weight once they reach middle age.

      Middle-aged Maine coons--between the ages of 5 and 10 years--are susceptible to obesity. TheCatSite.com recommends feeling a cat's ribs along its side: If the ribs can easily be counted, the cat is probably at a healthy weight. Cats that are spayed or neutered should not weigh any more than an unaltered animal. Neutered cats require fewer calories per day than an intact cat.
