Fluffie, the senior cat, went missing last night. It appears that she got off the roof, sought admittance at the front door (after the humans had gone to bed), and was attacked there presumably by another cat. We try not to worry: at our previous dwelling, where she regularly went out to hunt rodents, she was absent a few times for several days at a time.
Pillow, despite his “all you can eat” diet, is not fattening up rapidly enough to make a convincing substitute for Fluffie.
Update: After presumably sleeping under a bush all day, Fluffie returned late the following night. She was admitted by my housemate, who did not happen to mention whether she was reeking of cheap booze.
