Although most domestic cats are relatively small, there are a few particularly large breeds whose individual members can reach truly impressive lengths. One of these is the Maine Coon, widely recognized as the largest domestic cat breed.

It’s Not Decided by Weight

For many decades, the Guinness World Records ranked the largest animals by body weight. That’s how an Australian cat named Himmy became the record holder, reaching an astonishing weight of 21.3 kilograms. Himmy passed away in 1986 and was the last cat to hold the title of “heaviest cat.” In 1998, Guinness decided to discontinue the category and replace it with the titles of longest and tallest cat. The change was intended to discourage people from overfeeding their pets simply to break records.

How a Cat Becomes a Guinness Record Holder

At Guinness World Records, earning the title of “longest domestic cat” is far more complex than simply measuring your pet at home with a tape measure. Strict rules and documentation requirements must be met for a record to be officially certified. A cat’s length is measured from the tip of the nose all the way to the end of the tail, with the body fully extended. Guinness emphasizes that the measurement must be taken in a natural position—meaning the animal cannot be forcibly stretched or pulled to achieve a greater result.

Cats must be measured according to clearly defined rules

The measuring process is usually supervised by a veterinarian, an official expert, or another credible witness. Detailed photo and video documentation is also required for the record application. Owners must provide footage from multiple angles to prove the authenticity of the measurement, along with written witness statements and accurate data sheets. In many cases, the cat’s health condition must also be verified, especially since Guinness has placed increasing emphasis on animal welfare standards in recent decades.

Stewie, the World’s Longest Cat

The current all-time record holder is a silver tabby Maine Coon named Mymains Stewart Gilligan, better known as Stewie. Measured from nose to tail tip, Stewie was an incredible 123 cm (48.5 inches) long. For comparison, an average domestic cat is roughly 63–71 cm long. Stewie lived in the United States with his owners and was not only a beloved pet, but also a certified therapy cat. He perfectly embodied the “gentle giant” reputation often associated with Maine Coons. Stewie crossed the rainbow bridge in 2013.

Barivel, the Longest Living Cat

Guinness doesn’t only track the absolute record—it also keeps records for the longest living cat. That title currently belongs to Barivel, a brown tabby Maine Coon living in Vigevano, Italy, with his owner Cinzia Tinirello. Barivel falls just 3.3 centimeters short of Stewie’s record, measuring an impressive 120 cm in length. Although Guinness currently recognizes Barivel as the longest officially measured living domestic cat, exceptionally large cats occasionally appear that may come close to challenging his record. However, these cats do not always undergo the official verification process described above.

The Cat He Surpassed

Barivel exceeded his predecessor, Ludo, by less than one centimeter. Ludo lived in the United Kingdom with his owner, Kelsey Gill, who noticed when he was only 13 weeks old that he was growing far larger than his peers. Sadly, Ludo passed away in 2019 due to cancer.

Gentle Giants That Mature Slowly

The Maine Coon is one of the world’s largest domestic cat breeds, famous not only for its impressive size but also for its balanced and friendly personality. Originally from North America, its thick, water-resistant coat, powerful bone structure, and bushy tail evolved as adaptations to harsh climates. Maine Coons are slow-maturing cats and may continue growing until they are 3 to 5 years old, which is why their body length often far exceeds that of average domestic cats. While they are the most famous feline giants, other breeds can also grow to impressive sizes. The Norwegian Forest Cat and the Siberian Cat, for example, are similarly robust and long-bodied breeds.
