A Swedish family recoiled in terror when their trap did not immediately kill a 16-inch rat scurrying around their kitchen.

The gargantuan rodent, metal clasped tightly around its neck, powered through the pain and scampered off behind Signe Bengtsson-Korsas’ kitchen cabinets, The Sun reported.

“It was a monster, the worst thing I have ever seen,” she told the British tabloid.

Her husband, Erik, added, “The rat was so big it did not die.”

Eventually the squeaking stopped.

The nearly invincible beast was found lifeless behind their dishwasher.
