One of my cats does that too! We try to keep the dryer door closed because we are so afraid that we won't see her and we'll pop the door closed and turn on the dryer. My cousin lost her cat a few years ago that way. So scary.
Cute, though, aren't they? Funny little critters. If they aren't on my fabric or in my suitcase, they are in any little corner they can find. Don't blame them, looks comfy!
