That's kind of funny! I work in IT and the other day we had a girl bring her laptop in and the problem was the keyboard keys producing the wrong letters or two letters at a time when you only pressed the key once. The guy who worked on it took the keyboard off the laptop and discovered it was full of cat hair. After a thorough cleaning the keyboard worked fine and we advised the young lady she should keep her cat from laying on the keyboard. Evidently he likes the warmth coming from the laptop!
