This afternoon I had to get up early because I have a dental appointment. The new striped kitty (or old striped kitty, since she might be the one who visited last spring and vanished that summer) was on the back porch. I gave her a fresh bowl of food. A few minutes later I looked out and saw the gray cat eating. The striped kitty was no longer around, so they must have missed each other by a minute or two.
Gray cat drank some water from the bowl the birds bathe in, then rolled in the grass and went farther out back to pick out a shade-dappled spot for his afternoon nap. I guess he'll still be here when I get back from the dentist's office. I just hope no other kitties turn up in the meantime.
