The first time I saw it I was convinced that the cat was going to leap at the bird. Cats usually wind up other people's dogs for fun, but it looks like the bird has the upper hand here.
Stephen - I haven't seen that one before, thanks for posting it.
I had a budgie when I was young, one day it vanished and my mum told me that it had decided to fly back to Africa. I worried for ages about the other birds picking on him.
About ten years later mum admitted that he had just dropped dead and she put him in a cereal box and stuck him in the bin. ☺
