Longest Cats - Maine Coon

Maine Coon cats weigh about 8-18 pounds and grow as tall as 10 inches.


Maine Coon cats are sturdily built felines weighing anywhere from 8-18 pounds depending on age and sex. They are usually about 10-16 inches tall and a commendable 40 inches in length. Additionally, Maine Coon cats have muscular body structures with solid legs and broad chests.

The size of a full-grown male Maine coon cat is typically 15-25 pounds, while the female averages between 10-15 pounds. The height of the male cat is 10-16 inches and about 40 inches long. The female can stand about 8-14 inches tall and be the same length as the male.

Also, an overweight Maine Coon can attain a weight of about 35 pounds! This weight is rare but not impossible. It is important to note that Maine Coon cats are usually naturally big due to their slow growth rate, which allows their muscles and bone structure to develop very well. Maine Coon cats grow at the rate of two pounds per month from 3 months to 7 months.

However, certain factors such as health issues, small parents (parents being on the lower side of the growth spectrum), mixed breed, and diet deficiency also affect the overall growth of Maine Coons.

What is The Biggest Breed of a Maine Coon Cat?

The largest Maine Coon cat ever is as well a fair contender for the Maine Coon cat with the longest name. Mymains Stewart Gilligan measured an appealing 48.5 inches in length. Stewie was a gray tabby Maine Coon that was owned by Robin Hendrickson, who resided in Reno, Nevada.

Sadly, Stewie died of cancer in 2013, and ever since then, the title of the biggest Maine Coon cat has been awarded to Barivel, who is still living. He was born in September 2016, and as of May 2018, Barivel was 47.2 inches long. The name Barivel means “joker” or “clown” in Italian, and he lives in Vigevano in Italy.

Differences Between Maine Coon Cats and Regular House Cats

Although a Maine Coon cat and a regular house cat share many similarities as members of the Felinae family, they are different from each other. We’ll look at some of these differences below.

Maine Coon Cat vs Regular Cat: Size

Admittedly, Maine Coon cats are weightier than regular house cats. Male Maine Coons weigh about 15-25 pounds on average, while male house cats averagely weigh about 9-10 pounds. With this, it is apparent Maine Coon cats have a vivid weight advantage.

Female Maine Coon cats weigh about 10-15 pounds on average, while female house cats averagely weigh about 8-9 pounds. This implies that some of the largest regular house cats have the same weight as some smaller female Maine Coons. The biggest female Maine Coons are often weightier than the biggest regular male house cats.

Maine Coon Cat vs Regular Cat: Length

Length is another metric used to compare Maine Coon cats with other cats. The body length is determined from the nose to the base of the tail. Both male and female Maine Coons, on average, are 25-40 inches long, while male and female regular house cats weigh about 15-20 inches. This means even the shortest Maine Coon cats are longer than the longest regular house cats. 

Maine Coon Cat vs Regular Cat: Tails

Male and female Maine Coons have tails that are averagely about 12-18 inches in length, while the regular cats have an average tail length of just 10 inches. At the top of the spectrum, it is noticed that a Maine Coon cat has a tail that is almost twice the length of that of a regular cat.

Fun Facts About Maine Coon Cats
