I live in Florida, and we just had our first real cold front of the year, it got down to 46 last night. Last winter, from early December until some time in March, Arwen, my feral kitty, slept in the garage at night, and sometimes she stuck around until the late afternoon. She'd go out and visit my neighbors, she follows them and their dog on their evening walk, and then she'd come back when it was time for bed. Last night was her first night back in the garage. I thought maybe she'd be freaked out a little bit. She did check out every inch of the garage before she settled down, and let me pet her for a while. Then about 5 minutes into me spending time with her, she curls up in her little cat bed, and she's done. I leave a radio on very softly, and have a little nightlight. She took right to using the litter box again. She seems happy to be back. In fact, she stayed in there until about noon.
She's so funny, if we leave the door cracked, she will stand watch at the end of the garage, looking out all the while. But as soon as I close up the garage, she knows she can close her eyes and really sleep comfortably. That makes me happy. My neighbors and I estimate that she may have been in our neighborhood for as much as 10 years. She has her ear tipped, so at some point she was spayed and vaccinated. I thought maybe she'd start meowing to get out in the middle of the night. She did not make one peep all night long. I am so happy to have her in there for the winter
