If you think your cat is big, then you haven’t seen the giant kitty Fenrir, owned by William John Powers, a doctor in Farmington Hills, Michigan. Fenrir is 47.83 cm tall and the Guinness Book of Records recognizes him as the longest living domestic cat in the world.
Guinness says the name Fenrir comes from one of Saturn’s moons. However, like most cats, he has many nicknames in the family. “(I) call him Big Chungus or Chonk,” Powers says in a Guinness video about the record-breaking cat. “He grew up like Big Red Dog Clifford and just kept growing.”
Fenrir is an F2 Savannah cat. Savannah cats are a hybrid between a domestic cat and the serval, a wild cat native to Africa, and F2 means they are from the second generation of their distinctly different parent species. While Savannah cats tend to be tall, they average 35-43cm tall and Fenrir is 2.5cm taller than this range. Powers says cat height is measured from the cat’s shoulder blades while standing on all fours.
Fenrir’s height also allows him to do things other cats can’t. In a published video, it can be seen how he can stand on his hind legs and paw at the doorknob until the door opens. Powers says that because she’s a big eater, her cat is “inclined to steal things from the counter.”
Also, the cat is still growing. While he holds the world record for longest living cat, he’s still smaller than his brother Arcturus (who sadly died in a house fire in 2017) who holds the record for the tallest cat of all time. Arcturus was 48.4 cm tall. Although these cats do not live at the same time, their parents are the same.
Powers also owns Altair, the world’s longest-tailed cat in a living pet cat at 40.82 cm. And Cygnus, another cat that Powers lost in the 2017 fire, still holds the record for longest tail of all time, at 44.65 cm. Altair and Cygnus are Maine Coon cats.
