In this article, we’ll get to know the top five biggest cat breeds on Earth!

At the large end of the spectrum, you’ll find cats that have adapted to cold climates, necessitating big paws and massive tails. Others are distinctively tall and leggy.

Some of the largest cat breeds are domesticated cats little more than a few generations away from their wildcat roots. These exotic hybrids include the Cheetoh, Savannah, and Chausie.

How Big Is The World’s Longest Domesticated Cat?

In the Guinness Book of World Records, the world’s largest cats are determined by length rather than weight.

Currently, the world’s longest living cat is a Maine Coon named Ludo, who measures 118.3 centimeters or 45.6 inches long!. From nose tip to the end of his tail, Ludo is about as long as the average six-year-old human is tall. The longest cat ever was also a Maine Coon. Stewie measured 123.19 cm or 48.5 inches long.

How Big Is The World’s Heaviest Domesticated Cat?

Although the world’s largest cat breeds are above average in weight, any cat can be obese. Therefore, the world records tend to go to overweight cats rather than exceptionally large breeds.

To discourage people from feeding their cats into obesity and disease for the sake of stardom, the world’s heaviest cats are no longer recorded in the Guinness Book of World Records.

The heaviest cat on record died at age ten in 1986. At the time, Himmy weighed 21.3 kg or 46.8 lbs

Maine Coon

  • Origin: Maine, United States
  • Adult Weight: 11-25 lbs
  • Height: 10-16 ‎in
  • Lifespan: 13-16 Years

The true history of this fluffy American native is one cloaked in myth and legend. One tale asserts that the Maine Coon resulted from a cross between a raccoon and a domesticated cat, lending the breed its fluffy striped tail and its name.

Another more genetically plausible origin story involves a terrified Marie Antoinette. Fearing her ultimate demise at the hands of French Revolutionaries, she attempted to travel across the sea with her six favorite Turkish Angora cats. According to the legend, Marie never made it to the States, but at least some of her cats did. Once in New England, the Turkish Angoras bred with local cats and evolved into the Maine Coon.

Another hypothesis holds that the cat may have originated on ships managed by Captain Charles Coone, who traveled in the 1700s from Europe to New England, bringing longhaired European cats like the Norwegian Forest Cat.

This theory holds more weight – the similarity between these Northern European cats and the Maine Coon are striking and match up with the human history of the time.

Regardless of its background, the Maine Coon today is clearly made for harsh, cold environments.

Subsequent generations are labeled F2, F3, and so on. Members of the F1 and F2 generation are the largest, thanks to the influence of the serval genetics. These medium-sized wild cats weigh around 26 pounds as adults and some Savannahs reach a similarly high weight.

These cats are densely muscled and leggy, with short spotted coats and large, cupped round ears.

They’re lanky, muscular cats with exceptionally long legs. Their height is an impressive 14-18” at the shoulder.

In addition to a wild appearance, they retain the jungle cat’s passion for adventure. The Chausie personality is active, intelligent, and sociable, and they’re best suited to experienced, passionate owners who can dedicate time to an energetic and headstrong feline.

      Hi Marilyn, good comment! The Siberian is, indeed, quite a large breed, and it could rank among the biggest domesticated cat breeds in the world, but it just didn’t happen to make it into this particular list of five breeds.
