If you have cats and a computer you know what cats do, they seem to like walking on the keyboard.
Funny things happen, like they seem to be able to bring up the word search function and other stuff like that.
Well, with Karmic Koala what happens now is the cats get barked at, they walk on the keyboard and Ubuntu goes 'roof' 'roof' 'roof'.

I have seen a cat detector program for MS that detects 'cats on keyboard' it ignores multiple keys pressed at once assuming a cat crossing.

Is this Ubuntu's cat detector?
If not, it should be, it's pretty funny!
