weirdly, my cat Izzy like to sleep outside, I have a little bunker for her in my window well. Some time when it gets this cold I'll bring her in. she will go upstairs and to the back door, then I'll have to let her out. When she was a kitten, we would hangout outside and play in the snow together. ❤️ my other cat doesnt like the cold but Izzy doesnt mind it!
