I forgot to tell you guys, but the cat reappeared after an absence of five days. [Full disclosure: it is nearly impossible to get a cat to look into the camera.] Did her "owner" (the guy who lives in the condos across the street and goes on business trips without making any provisions for her to eat or drink) keep her inside? Did she find someone else who felt sorry for her? No idea, but I'm just glad to know she's not dead.
My mom christened her after she miraculously appeared from the county pound, 30 miles, two freeways and one river away (her "owner" actually sprung her, and then turned her out with no food again).
Mom calls her Yo-Yo.
She's certainly living up to her name.
