Have you seen that movie "The Losers"?  There's a scene in it where Captain America Chris Evans says, "Cats are not to be trusted."

This statement is totally proven by the following video.  A cat is standing in a window, barking like a dog, until the owner catches it.  The cat at least has the decency to look ashamed and switch to a meow.  You have to admit, the beastie does an amazing dog impression!

They may not be trustworthy, but they are hysterical!

In case you haven't seen The Losers (great movie), here's the bit where Chris Evans talks about cats and trust.
