Leon Smith, 30, said he thought he felt his girlfriend, Sophie Merrell, nuzzling the back of his neck, so he rolled over for a cuddle, The Mirror reported Tuesday.
Smith said he was shocked to discover Merrell had already left for work and the warm body next to his was actually a fox that had come in through the cat door.
"I just couldn't believe it. It was so calm, just staring at me," Smith said.
Smith said he chased the fox out of the house and the couple are now considering getting rid of the cat door to keep their home safe from future visits.
