Houseguest no longer, the orange kitty went home today. I put a "found cat" ad on our local news blog and the cat's mother, who had been away on vacation and came home last night to find her cat missing, called me this morning. She lives a block away and came right over with a carrier to pick her up.
Turns out the cat sitter, her neighbor's teenage daughter, had left the door open on her first night and the cat had gotten out then. By the time she chose my patio umbrella to camp on, she'd been out for two days!
Marigold's real name, by the way, is "Anthem," for the fact that she never, ever stops talking.
So that's the end of our tale. All's well that ends well - the kitty's home, her mom's happy and I don't have ten cats anymore.
