The ears of Lucky, her chihuahua and miniature pinscher mix, are pictured here, frozen at the sight of a sworn enemy. I have no doubt this cat could take him down! O'Donnell says. We've seen him a few times, monitoring the neighbourhood from this window. The image's slanted sidewalk is very characteristic of hilly San Francisco. I had to back up a bit and crouch down to get the shot, O'Donnell says.
