The mostly white cat likes to perch on the fence on one side of the backyard - I think its home is nearby on that side. I finally captured the cat on the fence, and the cherry tomato plant below (sharing its cage with some self-sown morning glories), but the cat was in the process of coming down for pettins:

Then it proceeded to roll around on the lawn (visible in the rear, the two potted cherry tomatoes, in front of the old brick barbecue hearth):

I eventually came indoors and did some dishes. The cat apparently decided to come on exploratorily into the screen room, because all of a sudden the geriatric, creaky dog exploded past the kitchen table and threw himself down the steps and out into the yard as if he was still young. The cat had already vanished into thin air of course.
