I had a half breed Siamese neutered male. He used to sleep on the South porch in the warm sunshine in the months when the sun is over the southern hemisphere. It is pier and beam, 8' wide by 24 ft long, covered. One year a Mocking bird just couldn't stand the cat and kept at him. Just happened to be watching the day and time the boom fell.
The cat was lying in his usual position, but this time he had 1 eye open that I could see but the Mocking bird couldn't, coming from the other direction, thinking he'd come in on one side of the porch, take a nip at one of the cat's ears on a fly-by and go on down the porch and away.
Not this time. Bird got in the vulnerable spot and just as you said, one paw came up in a flash and wham. Bird was on the porch knocked cookoo. Feathers, the legs and beak are all that was left. I didn't call the sheriff either but probably should have as I was "aiding and abetting".....Mocking bird is the Texas State Bird. Grin.
