Back when I was a young idjit and fed my cats their dry food outside on a big, flat tray, the magpies were merciless in swooping down to steal it from them. But, we had a friend who had parrots and cats all of his life and they always got along.

That's a neat video, though I am not sure of their basis for thinking the crow saved the kitten's life. It wasn't clear how old the kitten was when the crow first came upon it. Cats are amazingly able to catch and eat as much as a bird.:-) Still neat to see them share and play.
