We don't mean to alarm you, but a Dublin family found this 24-inch-long furry friend in their attic after hearing a chewing sound.
The rat was described by city pest control workers as "one of the bigger rats" caught recently, which makes you worry about what else they've been finding.
Just last week a Swedish man found this beauty in his kitchen - but that was only 15 inches in length.
To get an idea of scale, at 24 inches including its tail, this rat really isn't far from the size of an average cat.
