Oh, funny story. Our other cat, vanished. Freaked out by the roofers. And we live out in the desert and have lost cats to coyotes before. I thought I heard her on the roof. Next AM roofers show up and almost finish the job. When they leave, I hear noises and it sounds like scratching in the AC vents. The cat does not have a loud cry, so I had been looking for her all night. About 1 AM, I hear the noises again and I call for her, and I hear her, I open the door to the AC/Heater unit and I can see her through a small hole, up in the roof.
So, I go up on the roof with a flashlight, find a hammer and an area they patched there, I could not get the nails out with a hammer, and when I tried to pul it up, the particle board just broke, but eventually I broke a big enough hole in the thing that the cat could get out, and she wouldn't come out, so I had to reach in and pull her out. Scraped my arm all up. She's still freaked out.
Woulda been pretty bad to lose both cats in one day.
