Now we bring you the unsettling revelation of a similarly-sized beast on these very shores.
Adrian Whitaker came face-to-face with the rodent in his Highgate kitchen after hearing the “snap” of a mousetrap underneath his dishwasher.

The rat was left dazed by the mousetrap, enabling Whitaker to remove it from the house.
He added: “I picked it up with a bag and frogmarched it out of the front door with my wife screaming behind me.
“I then took some firewood to it and it took a few hits to kill it. It’s the first time I’ve killed anything so I felt a bit of guilt after.”
While there is no official word on the size of Whitaker’s rat, the image shows the animal’s body alone measures the length of the 6ft 3 software developer's forearm.
As with this animal, the Swedish ratzilla was also snared by a mousetrap and clung onto life before noisily dying beneath a kitchen cabinet.
“It was a monster, the worst thing I have ever seen,” Signe Bengtsson-Korsas told The Sun.
