Omar stretches out to 1.2 metres (47.2 inches) and weighs in at 14 kg (30.8 pounds), according to the cat‘s owner, Melbourne resident Stephy Hirst.
“We were expecting about a nine-kilo cat,” said Hirst, who told the Maroondah Leader that Guinness World Records had reached out to her about Omar.
The current record holder at 118.33 cm (46.6 inches) is Ludo, another Maine Coon cat living in the United Kingdom.
Omar eats dry cat food and kangaroo meat, and has a relaxed life lounging around the house with dogs Rafiki and Penny, Hirst told Australia’s Seven Network.
Guinness World Records has yet to confirm if Omar takes the title.
Maine Coons are one of the largest breeds of domesticated felines in the world. They derive their name from the U.S. state of Maine, where it is the official state cat.
