I find that most stray cats like to have 2 doors, one on either end, offset. They have a fear of being trapped.
I too would worry about setting fire to the house. There are some "thingy's" (flat pillow like filled with ???) that you can put in a microwave for 2 min. and they'll stay warm for hours. Some people use them for beds.

But think about the draft!! We don't want them to catch a cold.
