I'm fairly certain they don't tell you during flight school to check for sleeping cats, but it's probably a good idea. Two people flying a small aircraft in Kourou, French Guiana over the weekend discovered they had a feline stowaway that had been sleeping on the plane's wing before takeoff. I'm not really sure who's more shocked, the cat or the people, but luckily everyone made it back on the ground in one piece.

 After a stunt like that, this cat's definitely gotta be down a couple lives.
