Cats & Birds Living Together--We're Talkin' Mass Hysteria Here!

Calling all bird behavior experts!

This video of a crow and kitten hanging out together--even the crow feeding the kitten showed up on Cute Overload. What is going on here? Confused crow? Are birds trying to reach a peace agreement to keep cats from killing them at feeders? Have crows become so smart that they have decided to attempt to join forces with cats to secure their place high on the food chain? Are crows trying to set a better example for Jim Stevenson? Or is this just some weird event that can never be fully explained or understood?
