The cat and the mocking bird are still out there. The mocking bird attacks have abated the last month and a half or so.
Strange to watch. The cat would be slowly walking oblivious to the bird who was hovering and attacking about a foot above the cat. Sort of like the old Peanuts character Pig Pen with his cloud of dust constantly around him. When the cat would lie down on the grass or in the street the bird would continue his attacking from above and on the ground as the cat ignored him. They would be doing this most of the day. Could be the cat enjoyed the activity.
