Devil Mice are simply the fabrication of retarded christian parents with no social lives. According to these fucked up people, devil mice are simply mice that are posessed by Satan. A devil mouse is usually .5-2 feet in length and weigh in at 25-10 lbs, They are bright red and have small horns poking out of the forehead.
This conspiracy is similar to the many theories regarding satanic cults, although this one was different, seeing as most people were smart enough to know that left-wing, devil worshipping mice would kidnap and rape their children.
These smart people happened to be atheists and unitarians, but thats about it. The mice were condemned by Pope Cedric the Entertainer and were presumed to be harbingers of the apocalypse. Nowadays no one cares about devil mice although some say they will strike again...
