Thanks everyone.

Livvy also survived her second night outside, but is spending tonight inside. I think we're getting somewhat of a storm and we don't have the second tarp yet.

I came up with a good idea to keep her somewhat insulated at night. Livvy doesn't really like the "rubbermaid" shelter we put in there, so she spent all last night on the large cat bed (the bluish one in the picture above) on top of a fleece blankie I gave her. I'm going to go to a fabric/crafty store to get some fabric and will pin (push pins?) material all around the side of the enclosure that don't back up to our apartment. I'll make it like curtains, so in the day time when its warm, I can open them. That way she'll be better protected against wind.

Luckily, we live in Southern California, so our temperatures are really mild most of the time. This will do until the colder part of winter. So that's good.
