If a cat catches a bird from the window sill and has him for about 30 seconds, would the cat kill him right away or just swat him around? My cat has caught a bird for the second time in a month (from the window sill, by pushing the screen out). I ran into the room about 30 seconds into the attack and stopped it and now don't know where the bird is, and if it's alive or dead. Am bracing myself for having to go dig around to find a bird body, but maybe he was just swatting the bird around?
