Well I don\'t mind mice but rats give me the \"Heebies\". :|~
About 15-20 years ago I worked in a computer centre which had Raised flooring for cable ducting etc. One day a colleague dropped a pound coin (£1) which fell through one of the vents into the void underneath. I ,being a gent, lifted the vent covers and dropped down into the space for her. Picked up the coin and several others of smaller denomination, turned around and came face to face with a rat.
Now I know that rats are only about 7-8 inches but this looked to be the size of a Spanial. (Bear in mind I\'m in a crawlspace about 1 metre high and without light.)
I leapt out of that space like a bloody ejector seat, and have never been able to face rats again. :|~
